Enum tidb_query_datatype::def::field_type::Collation[−][src]

#[repr(i32)]pub enum Collation {
    Binary,
    Utf8Mb4Bin,
    Utf8Mb4BinNoPadding,
    Utf8Mb4GeneralCi,
    Utf8Mb4UnicodeCi,
    Latin1Bin,
}

Valid values of tipb::FieldType::collate and tipb::ColumnInfo::collation.

Legacy Utf8Bin collator (was the default) does not pad. For compatibility, all new collation with padding behavior is negative.

Please refer to mysql/charset.go.

Implementations

`impl Collation`[src]

`pub fn from_i32(n: i32) -> Result<Self, DataTypeError>`[src]

Parse from collation id.

These are magic numbers defined in tidb, where positive numbers are for legacy compatibility, and all new clusters with padding configuration enabled will use negative numbers to indicate the padding behavior.
