Struct Input 

#[non_exhaustive]
pub struct Input<'a> {
    pub offset: u64,
    pub bytes: &'a [u8],
    pub total_len: Option<u64>,
}

Bytes offered to one step.

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.

offset: u64

Absolute offset of bytes[0] in the source.

bytes: &'a [u8]

The bytes. May be empty.

total_len: Option<u64>

Total source length, once the driver knows it.

Implementations

impl<'a> Input<'a>

pub const fn new(offset: u64, bytes: &'a [u8]) -> Input<'a>

bytes located at offset, total length unknown.

pub const fn empty() -> Input<'a>

No bytes: step without new input.

pub const fn with_total_len(self, total_len: u64) -> Input<'a>

The same input, carrying the total source length.

pub const fn with_total_len_opt(self, total_len: Option<u64>) -> Input<'a>

The same input, carrying the total source length if known.

pub const fn end(&self) -> u64

Absolute offset one past the last byte.

pub fn reaches_end(&self) -> bool

Whether these bytes run to the end of the source.

Trait Implementations

impl<'a> Clone for Input<'a>

fn clone(&self) -> Input<'a>

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

Performs copy-assignment from source.

impl<'a> Copy for Input<'a>

impl<'a> Debug for Input<'a>

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

fn eq(&self, other: &Input<'a>) -> bool

Equality operator ==.
