Struct object::read::Bytes

source ·
pub struct Bytes<'data>(pub &'data [u8]);
Expand description

A newtype for byte slices.

It has these important features:

  • no methods that can panic, such as Index
  • convenience methods for Pod types
  • a useful Debug implementation

Implementations§

source§

impl<'data> Bytes<'data>

source

pub fn len(&self) -> usize

Return the length of the byte slice.

source

pub fn is_empty(&self) -> bool

Return true if the byte slice is empty.

source

pub fn skip(&mut self, offset: usize) -> Result<(), ()>

Skip over the given number of bytes at the start of the byte slice.

Modifies the byte slice to start after the bytes.

Returns an error if there are too few bytes.

source

pub fn read_bytes(&mut self, count: usize) -> Result<Bytes<'data>, ()>

Return a reference to the given number of bytes at the start of the byte slice.

Modifies the byte slice to start after the bytes.

Returns an error if there are too few bytes.

source

pub fn read_bytes_at( self, offset: usize, count: usize, ) -> Result<Bytes<'data>, ()>

Return a reference to the given number of bytes at the given offset of the byte slice.

Returns an error if the offset is invalid or there are too few bytes.

source

pub fn read<T: Pod>(&mut self) -> Result<&'data T, ()>

Return a reference to a Pod struct at the start of the byte slice.

Modifies the byte slice to start after the bytes.

Returns an error if there are too few bytes or the slice is incorrectly aligned.

source

pub fn read_at<T: Pod>(self, offset: usize) -> Result<&'data T, ()>

Return a reference to a Pod struct at the given offset of the byte slice.

Returns an error if there are too few bytes or the offset is incorrectly aligned.

source

pub fn read_slice<T: Pod>(&mut self, count: usize) -> Result<&'data [T], ()>

Return a reference to a slice of Pod structs at the start of the byte slice.

Modifies the byte slice to start after the bytes.

Returns an error if there are too few bytes or the offset is incorrectly aligned.

source

pub fn read_slice_at<T: Pod>( self, offset: usize, count: usize, ) -> Result<&'data [T], ()>

Return a reference to a slice of Pod structs at the given offset of the byte slice.

Returns an error if there are too few bytes or the offset is incorrectly aligned.

source

pub fn read_string(&mut self) -> Result<&'data [u8], ()>

Read a null terminated string.

Does not assume any encoding. Reads past the null byte, but doesn’t return it.

source

pub fn read_string_at(self, offset: usize) -> Result<&'data [u8], ()>

Read a null terminated string at an offset.

Does not assume any encoding. Does not return the null byte.

source

pub fn read_uleb128(&mut self) -> Result<u64, ()>

Read an unsigned LEB128 number.

source

pub fn read_sleb128(&mut self) -> Result<i64, ()>

Read a signed LEB128 number.
