Struct RotationPolicy 

pub struct RotationPolicy {
    pub size_of_journal_file: Option<u64>,
    pub duration_of_journal_file: Option<Duration>,
    pub number_of_entries: Option<usize>,
}

Controls when journal files should be rotated

A file rotates when any configured limit is exceeded. If all fields are None, files never rotate automatically.

Fields

size_of_journal_file: Option<u64>

Maximum file size

duration_of_journal_file: Option<Duration>

Maximum duration of head/tail entries

number_of_entries: Option<usize>

Maximum number of log entries

Implementations

impl RotationPolicy

pub fn with_size_of_journal_file( self, size_of_journal_file: u64, ) -> RotationPolicy

Specifies the maximum journal file size.

pub fn with_duration_of_journal_file( self, duration_of_journal_file: Duration, ) -> RotationPolicy

Specifies the maximum duration between head/tail entry.

pub fn with_number_of_entries(self, number_of_entries: usize) -> RotationPolicy

Specifies maximum number of entries.
