Struct SourceSchedulerPolicy 

pub struct SourceSchedulerPolicy { /* private fields */ }

Native source scheduling controls.

Implementations

impl SourceSchedulerPolicy

pub const fn serialized() -> Self

Creates a source scheduler with one read at a time and no prefetch.

pub const fn new(max_source_reads_in_flight: usize) -> Self

Sets the maximum concurrent source reads. Zero is rejected by Self::validate; the default permits two reads.

pub const fn max_source_reads_in_flight(self) -> usize

Returns the configured concurrent source-read bound.

pub const fn enables_prefetch(self) -> bool

Returns whether the policy permits more than one concurrent source read.

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

Rejects zero concurrent source reads with InvalidConfiguration.
