Struct Fetch 

#[non_exhaustive]
pub struct Fetch {
    pub priority: u8,
    pub frame_start: u64,
}

Options for a one-shot track::Consumer::fetch_group of a past group.

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.

priority: u8

Delivery priority for the fetched group’s stream. Defaults to 0.

frame_start: u64

Index of the first frame to fetch within the group. Defaults to 0, the whole group.

Use this to fill a hole left by a route change: the group’s head is already cached locally and only the tail is missing.

There is no matching end: a fetch always runs to the end of the group, and a caller wanting less caps the returned consumer with Consumer::set_frames. Stopping the fetch short would put a group in the cache that is indistinguishable from a complete one, so a later fetch of the whole group would resolve from it and come up short.

Implementations

impl Fetch

pub fn with_priority(self, priority: u8) -> Self

Set the delivery priority, returning self for chaining.

pub fn with_frame_start(self, frame_start: u64) -> Self

Set the first frame to fetch, returning self for chaining.

Trait Implementations

impl Clone for Fetch

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Fetch

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

Formats the value using the given formatter.

impl Default for Fetch

fn default() -> Self

Returns the “default value” for a type.
