Struct polyverse_file_rotate::FileRotate

pub struct FileRotate { /* fields omitted */ }

The main writer used for rotating logs.

Implementations

impl FileRotate

pub fn new<P: AsRef<Path>>(
    path: P,
    rotation_mode: RotationMode,
    max_file_number: usize
) -> Result<Self, Error>

Create a new FileRotate.

The basename of the path is used to create new log files by appending an extension of the form .N, where N is 0..=max_file_number.

rotation_mode specifies the limits for rotating a file.

Trait Implementations

impl Debug for FileRotate

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

Formats the value using the given formatter.

impl Write for FileRotate

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

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

pub 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.
