Struct FfiByteSlice

#[repr(C)]
pub struct FfiByteSlice<'a> {
    pub data: *const u8,
    pub data_len: usize,
    /* private fields */
}

A Rust u8 slice, but compatible with FFI. Assume the lifetime is only valid until the callee returns to the caller.

Fields

data: *const u8

A pointer to the data

data_len: usize

The number of bytes we are pointing at

Implementations

impl<'a> FfiByteSlice<'a>

pub fn new(s: &'a [u8]) -> FfiByteSlice<'a>

Create a new byte slice we can send over the FFI.

pub fn empty() -> FfiByteSlice<'static>

Make an empty slice.

pub fn as_slice(&self) -> &[u8]

Turn this byte slice into a Rust byte slice.

Trait Implementations

impl<'a> Clone for FfiByteSlice<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FfiByteSlice<'_>

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

Formats the value using the given formatter.

impl<'a> From<&'a [u8]> for FfiByteSlice<'a>

fn from(input: &'a [u8]) -> FfiByteSlice<'a>

Convert from a Rust byte slice into an FFI compatible byte slice

impl<'a> Ord for FfiByteSlice<'a>

fn cmp(&self, rhs: &FfiByteSlice<'a>) -> Ordering

Compare two ApiByteSlices.

We just make some actual slices and compare then.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for FfiByteSlice<'a>

fn eq(&self, rhs: &FfiByteSlice<'a>) -> bool

Check if two ApiByteSlices are equal.

We just make some actual slices and compare then.

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

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

impl<'a> PartialOrd for FfiByteSlice<'a>

fn partial_cmp(&self, rhs: &FfiByteSlice<'a>) -> Option<Ordering>

Compare two ApiByteSlices.

We are Ord so we can defer to that.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
