Struct log4rs::append::rolling_file::policy::compound::roll::fixed_window::FixedWindowRollerBuilder

pub struct FixedWindowRollerBuilder { /* private fields */ }

A builder for the FixedWindowRoller.

Implementations

impl FixedWindowRollerBuilder

pub fn base(self, base: u32) -> FixedWindowRollerBuilder

Sets the base index for archived log files.

Defaults to 0.

pub fn build(self, pattern: &str, count: u32) -> Result<FixedWindowRoller>

Constructs a new FixedWindowRoller.

pattern is either an absolute path or lacking a leading /, relative to the cwd of your application. The pattern must contain at least one instance of {}, all of which will be replaced with an archived log file’s index.

If the file extension of the pattern is .gz and the gzip Cargo feature is enabled, the archive files will be gzip-compressed. If the extension is .gz and the gzip feature is not enabled, an error will be returned.

count is the maximum number of archived logs to maintain.
