Struct kiwi_schema::ByteBuffer [−][src]
pub struct ByteBuffer<'a> { /* fields omitted */ }
A Kiwi byte buffer meant for reading.
Example usage:
use std::borrow::Cow; let mut bb = kiwi_schema::ByteBuffer::new(&[240, 159, 141, 149, 0, 133, 242, 210, 237]); assert_eq!(bb.read_string(), Ok(Cow::Borrowed("🍕"))); assert_eq!(bb.read_var_float(), Ok(123.456));
Methods
impl<'a> ByteBuffer<'a>
[src]
impl<'a> ByteBuffer<'a>
pub fn new(data: &[u8]) -> ByteBuffer
[src]
pub fn new(data: &[u8]) -> ByteBuffer
Create a new ByteBuffer that wraps the provided byte slice. The lifetime of the returned ByteBuffer must not outlive the lifetime of the byte slice.
pub fn data(&self) -> &'a [u8]
[src]
pub fn data(&self) -> &'a [u8]
Retrieves the underlying byte slice.
pub fn index(&self) -> usize
[src]
pub fn index(&self) -> usize
Retrieves the current index into the underlying byte slice. This starts
off as 0 and ends up as self.data().len()
when everything has been
read.
pub fn read_bool(&mut self) -> Result<bool, ()>
[src]
pub fn read_bool(&mut self) -> Result<bool, ()>
Try to read a boolean value starting at the current index.
pub fn read_byte(&mut self) -> Result<u8, ()>
[src]
pub fn read_byte(&mut self) -> Result<u8, ()>
Try to read a byte starting at the current index.
pub fn read_bytes(&mut self, len: usize) -> Result<&'a [u8], ()>
[src]
pub fn read_bytes(&mut self, len: usize) -> Result<&'a [u8], ()>
Try to read a byte starting at the current index.
pub fn read_var_int(&mut self) -> Result<i32, ()>
[src]
pub fn read_var_int(&mut self) -> Result<i32, ()>
Try to read a variable-length signed 32-bit integer starting at the current index.
pub fn read_var_uint(&mut self) -> Result<u32, ()>
[src]
pub fn read_var_uint(&mut self) -> Result<u32, ()>
Try to read a variable-length unsigned 32-bit integer starting at the current index.
pub fn read_var_float(&mut self) -> Result<f32, ()>
[src]
pub fn read_var_float(&mut self) -> Result<f32, ()>
Try to read a variable-length 32-bit floating-point number starting at the current index.
pub fn read_string(&mut self) -> Result<Cow<'a, str>, ()>
[src]
pub fn read_string(&mut self) -> Result<Cow<'a, str>, ()>
Try to read a UTF-8 string starting at the current index. This string is returned as a slice so it just aliases the underlying memory.
