Enum Extent 

pub enum Extent<T> {
    Complete(T),
    NeedMore {
        up_to: u64,
    },
}

Result of a bounded metadata probe.

Variants

Complete(T)

The metadata region is fully present in the prefix; here is the parse.

NeedMore

The prefix is too short. Read at least up to up_to bytes (capped at the file length) and retry. up_to is strictly greater than the current prefix length unless the parser cannot bound its need, in which case the caller falls back to reading the whole file.

Fields

up_to: u64

Trait Implementations

impl<T: Clone> Clone for Extent<T>

fn clone(&self) -> Extent<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Extent<T>

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

Formats the value using the given formatter.

impl<T: Eq> Eq for Extent<T>

impl<T: PartialEq> PartialEq for Extent<T>

fn eq(&self, other: &Extent<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
