Struct SnapReader 

pub struct SnapReader<'a> {
    pub data: &'a [u8],
    pub cursor: usize,
    pub ok: bool,
}

Bounds-checked little-endian reader over a snapshot image. A short or corrupt image trips ok instead of panicking, mirroring the C b2SnapReader contract. (b2SnapReader)

Fields

data: &'a [u8]

cursor: usize

ok: bool

Implementations

impl<'a> SnapReader<'a>

pub fn new(data: &'a [u8]) -> SnapReader<'a>

pub fn r_u16(&mut self) -> u16

pub fn r_u32(&mut self) -> u32

pub fn r_i32(&mut self) -> i32

pub fn r_u64(&mut self) -> u64

pub fn r_f32(&mut self) -> f32

pub fn r_f64(&mut self) -> f64

pub fn r_bool(&mut self) -> bool

pub fn r_u8(&mut self) -> u8

pub fn check_count(&mut self, count: i32, min_stream_bytes: usize) -> bool

Guard an element count against the remaining stream so a corrupt count cannot force a huge allocation. (b2SnapCheckCount)

pub fn r_header(&mut self) -> SnapHeader

Trait Implementations

impl<'a> Debug for SnapReader<'a>

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

Formats the value using the given formatter.
