Struct rolling_file::RollingFileAppender
source · pub struct RollingFileAppender<RC>where
RC: RollingCondition,{ /* private fields */ }
Expand description
Writes data to a file, and “rolls over” to preserve older data in a separate set of files. Old files have a Debian-style naming scheme where we have base_filename, base_filename.1, …, base_filename.N where N is the maximum number of rollover files to keep.

RC: RollingCondition,
impl<RC> RollingFileAppender<RC>where
RC: RollingCondition,
sourcepub fn new<P>(
path: P,
condition: RC,
max_files: usize
) -> Result<RollingFileAppender<RC>>where
P: AsRef<Path>,
pub fn new<P>(
path: P,
condition: RC,
max_files: usize
) -> Result<RollingFileAppender<RC>>where
P: AsRef<Path>,
Creates a new rolling file appender with the given condition. The parent directory of the base path must already exist.
sourcepub fn new_with_buffer_capacity<P>(
path: P,
condition: RC,
max_files: usize,
buffer_capacity: usize
) -> Result<RollingFileAppender<RC>>where
P: AsRef<Path>,
pub fn new_with_buffer_capacity<P>(
path: P,
condition: RC,
max_files: usize,
buffer_capacity: usize
) -> Result<RollingFileAppender<RC>>where
P: AsRef<Path>,
Creates a new rolling file appender with the given condition and write buffer capacity. The parent directory of the base path must already exist.
sourcepub fn condition_ref(&self) -> &RC
pub fn condition_ref(&self) -> &RC
Returns a reference to the rolling condition
sourcepub fn condition_mut(&mut self) -> &mut RC
pub fn condition_mut(&mut self) -> &mut RC
Returns a mutable reference to the rolling condition, possibly to mutate its state dynamically.
