Struct log_wrappers::test_util::SyncLoggerBuffer

pub struct SyncLoggerBuffer(Arc<Mutex<Vec<u8>>>);

A buffer which can be served as a logging destination while being able to access its content.

Implementations

impl SyncLoggerBuffer

pub fn new() -> SyncLoggerBuffer

Creates a new instance.

pub fn build_logger(&self) -> Logger

Builds a slog::Logger over this buffer which uses compact format and always output TIME in the time field.

fn lock(&self) -> MutexGuard<'_, Vec<u8>>

pub fn as_string(&self) -> String

Clones the buffer and creates a String.

Panics if the buffer is not a valid UTF-8 string.

pub fn clear(&self)

Clears the buffer.

Trait Implementations

impl Clone for SyncLoggerBuffer

fn clone(&self) -> SyncLoggerBuffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for SyncLoggerBuffer

fn default() -> SyncLoggerBuffer

Returns the “default value” for a type.

impl Write for SyncLoggerBuffer

fn write(&mut self, data: &[u8]) -> Result<usize>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

pub fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

pub fn is_write_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

pub fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

pub fn write_all_vectored(
    &mut self,
    bufs: &mut [IoSlice<'_>]
) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

pub fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

pub fn by_ref(&mut self) -> &mut Self

Creates a “by reference” adaptor for this instance of Write.
