Struct SegmentConfig 

#[non_exhaustive]
pub struct SegmentConfig {
    pub max_batch_events: usize,
    pub flush_interval_secs: u64,
    pub max_size_bytes: u64,
    pub compression_level: i32,
    pub cipher: Option<Box<dyn SegmentCipher>>,
}

Configuration knobs for SegmentBuffer.

This struct is #[non_exhaustive]: new fields may be added in any release without breaking semver. Construct via SegmentConfig::default() and then mutate the public fields you care about:

use segment_buffer::SegmentConfig;

let mut config = SegmentConfig::default();
config.max_batch_events = 64;
config.flush_interval_secs = 1;

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_batch_events: usize

Max events accumulated in RAM before auto-flush (default: 256).

flush_interval_secs: u64

Max seconds between flushes. An append after this interval triggers a flush even if the batch threshold hasn’t been reached (default: 5s).

max_size_bytes: u64

Max total disk usage before the buffer reports overload pressure (default: 10 GB).

compression_level: i32

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

cipher: Option<Box<dyn SegmentCipher>>

Optional cipher for encrypting segment files at rest. When None, segments are written as plaintext zstd+CBOR.
