Enum tidb_query_datatype::codec::mysql::time::Tz

pub enum Tz {
    Offset(FixedOffset),
    Name(Tz),
    Local(Local),
}

A time zone represented by either offset (i.e. +8) or name (i.e. Asia/Shanghai). In addition, local time zone is also valid.

Variants

Offset(FixedOffset)

A time zone specified by offset seconds.

Name(Tz)

A time zone specified by name (in IANA database).

Local(Local)

A local time zone.

Implementations

impl Tz

pub fn from_offset(secs: i64) -> Option<Self>

Constructs a time zone from the offset in seconds.

pub fn from_tz_name(name: &str) -> Option<Self>

Constructs a time zone from the name. If the specified time zone name is system, a local time zone will be constructed.

pub fn utc() -> Self

Constructs a UTC time zone.

pub fn local() -> Self

Constructs a local time zone.

Trait Implementations

impl Clone for Tz

fn clone(&self) -> Tz

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Tz

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Tz

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl TimeZone for Tz

type Offset = TzOffset

An associated offset type. This type is used to store the actual offset in date and time types. The original TimeZone value can be recovered via TimeZone::from_offset.

fn from_offset(offset: &Self::Offset) -> Self

Reconstructs the time zone from the offset.

fn offset_from_local_date(&self, local: &NaiveDate) -> LocalResult<Self::Offset>

Creates the offset(s) for given local NaiveDate if possible.

fn offset_from_local_datetime(
    &self,
    local: &NaiveDateTime
) -> LocalResult<Self::Offset>

Creates the offset(s) for given local NaiveDateTime if possible.

fn offset_from_utc_date(&self, utc: &NaiveDate) -> Self::Offset

Creates the offset for given UTC NaiveDate. This cannot fail.

fn offset_from_utc_datetime(&self, utc: &NaiveDateTime) -> Self::Offset

Creates the offset for given UTC NaiveDateTime. This cannot fail.

fn from_local_date(&self, local: &NaiveDate) -> LocalResult<Date<Self>>

Converts the local NaiveDate to the timezone-aware Date if possible.

fn from_local_datetime(
    &self,
    local: &NaiveDateTime
) -> LocalResult<DateTime<Self>>

Converts the local NaiveDateTime to the timezone-aware DateTime if possible.

fn from_utc_date(&self, utc: &NaiveDate) -> Date<Self>

Converts the UTC NaiveDate to the local time. The UTC is continuous and thus this cannot fail (but can give the duplicate local time).

fn from_utc_datetime(&self, utc: &NaiveDateTime) -> DateTime<Self>

Converts the UTC NaiveDateTime to the local time. The UTC is continuous and thus this cannot fail (but can give the duplicate local time).

pub fn ymd(&self, year: i32, month: u32, day: u32) -> Date<Self>

Makes a new Date from year, month, day and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

pub fn ymd_opt(
    &self,
    year: i32,
    month: u32,
    day: u32
) -> LocalResult<Date<Self>>

Makes a new Date from year, month, day and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

pub fn yo(&self, year: i32, ordinal: u32) -> Date<Self>

Makes a new Date from year, day of year (DOY or “ordinal”) and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

pub fn yo_opt(&self, year: i32, ordinal: u32) -> LocalResult<Date<Self>>

Makes a new Date from year, day of year (DOY or “ordinal”) and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

pub fn isoywd(&self, year: i32, week: u32, weekday: Weekday) -> Date<Self>

Makes a new Date from ISO week date (year and week number), day of the week (DOW) and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE. The resulting Date may have a different year from the input year.

pub fn isoywd_opt(
    &self,
    year: i32,
    week: u32,
    weekday: Weekday
) -> LocalResult<Date<Self>>

Makes a new Date from ISO week date (year and week number), day of the week (DOW) and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE. The resulting Date may have a different year from the input year.

pub fn timestamp(&self, secs: i64, nsecs: u32) -> DateTime<Self>

Makes a new DateTime from the number of non-leap seconds since January 1, 1970 0:00:00 UTC (aka “UNIX timestamp”) and the number of nanoseconds since the last whole non-leap second.

pub fn timestamp_opt(
    &self,
    secs: i64,
    nsecs: u32
) -> LocalResult<DateTime<Self>>

Makes a new DateTime from the number of non-leap seconds since January 1, 1970 0:00:00 UTC (aka “UNIX timestamp”) and the number of nanoseconds since the last whole non-leap second.

pub fn timestamp_millis(&self, millis: i64) -> DateTime<Self>

Makes a new DateTime from the number of non-leap milliseconds since January 1, 1970 0:00:00 UTC (aka “UNIX timestamp”).

pub fn timestamp_millis_opt(&self, millis: i64) -> LocalResult<DateTime<Self>>

Makes a new DateTime from the number of non-leap milliseconds since January 1, 1970 0:00:00 UTC (aka “UNIX timestamp”).

pub fn timestamp_nanos(&self, nanos: i64) -> DateTime<Self>

Makes a new DateTime from the number of non-leap nanoseconds since January 1, 1970 0:00:00 UTC (aka “UNIX timestamp”).

pub fn datetime_from_str(
    &self,
    s: &str,
    fmt: &str
) -> Result<DateTime<Self>, ParseError>

Parses a string with the specified format string and returns a DateTime with the current offset. See the format::strftime module on the supported escape sequences.
