Struct SegmentConfigBuilder 

pub struct SegmentConfigBuilder { /* private fields */ }

Ergonomic builder for SegmentConfig.

SegmentConfig is #[non_exhaustive], so direct struct-literal construction is forbidden outside the crate. The builder is the recommended way for callers to override one or two fields without re-typing every default.

use segment_buffer::{FlushPolicy, SegmentConfig};
use std::time::Duration;

let config = SegmentConfig::builder()
    .flush_policy(FlushPolicy::Batch(64))
    .compression_level(6)
    .build();
assert_eq!(config.flush_policy, FlushPolicy::Batch(64));
assert_eq!(config.compression_level, 6);
// Untouched fields fall back to Default.
assert_eq!(config.max_size_bytes, 10 * 1024 * 1024 * 1024);

Implementations

impl SegmentConfigBuilder

pub fn flush_policy(self, policy: FlushPolicy) -> Self

Override the auto-flush policy. See FlushPolicy for variants.

pub fn flush_at_batch_size(self, batch_size: usize) -> Self

Convenience: install a FlushPolicy::Batch(batch_size).

pub fn flush_at_interval(self, interval: Duration) -> Self

Convenience: install a FlushPolicy::Interval(interval).

pub fn flush_at_batch_or_interval( self, batch_size: usize, interval: Duration, ) -> Self

Convenience: install a FlushPolicy::BatchOrInterval { .. } with both triggers set.

pub fn flush_manually(self) -> Self

Convenience: install a FlushPolicy::Manual (no auto-flush).

pub fn max_size_bytes(self, max_size_bytes: u64) -> Self

Override the disk-usage ceiling that triggers is_overloaded().

pub fn compression_level(self, compression_level: i32) -> Self

Override the zstd compression level (1–22; 3 is fast with a good ratio).

pub fn cipher(self, cipher: Box<dyn SegmentCipher>) -> Self

Install a SegmentCipher so segment payloads are encrypted at rest.

pub fn build(self) -> SegmentConfig

Materialise the configured SegmentConfig.

Trait Implementations

impl Debug for SegmentConfigBuilder

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

Formats the value using the given formatter.
