Struct WalOptions 

pub struct WalOptions {
    pub entry_retention: Duration,
    pub segments_per_retention_period: u32,
}

Configuration options for WAL behavior.

Examples

use nano_wal::WalOptions;
use std::time::Duration;

let options = WalOptions::default()
    .retention(Duration::from_secs(3600))
    .segments_per_retention_period(5);

Fields

entry_retention: Duration

Duration for which entries are retained before expiration

segments_per_retention_period: u32

Number of segments per retention period for rotation

Implementations

impl WalOptions

pub fn with_retention(retention: Duration) -> Self

Creates options with custom retention duration.

Examples

use nano_wal::WalOptions;
use std::time::Duration;

let options = WalOptions::with_retention(Duration::from_secs(3600));

pub fn with_segments_per_retention_period(segments: u32) -> Self

Creates options with custom segment count.

Examples

use nano_wal::WalOptions;

let options = WalOptions::with_segments_per_retention_period(20);

pub fn retention(self, retention: Duration) -> Self

Sets retention period (chainable).

pub fn segments_per_retention_period(self, segments: u32) -> Self

Sets segments per retention period (chainable).

pub fn validate(&self) -> Result<()>

Validates the configuration.

Errors

Returns WalError::InvalidConfig if:

• entry_retention is zero
• segments_per_retention_period is zero
