Struct LeBuf 

pub struct LeBuf { /* private fields */ }

The write half: an append-only buffer with the same field vocabulary, plus the patch-back-in-place the bbi writer needs for counts and offsets whose values are only known once what follows them has been built.

Implementations

impl LeBuf

pub fn new() -> Self

pub fn with_capacity(n: usize) -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn clear(&mut self)

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

pub fn into_bytes(self) -> Bytes

pub fn put_bytes(&mut self, data: &[u8])

pub fn put_zeros(&mut self, n: usize)

pub fn put_padded_str(&mut self, s: &str, width: usize) -> Result<()>

Zero-padded to a fixed width, as the chromosome B+ tree stores keys. A name longer than width is an error rather than a truncation: a silently truncated key breaks chromosome resolution in a way that only surfaces at read time.

impl LeBuf

pub fn put_u8(&mut self, value: u8)

pub fn set_u8(&mut self, offset: usize, value: u8)

Overwrite a field already placed. Panics if it does not fit, which would be a bug in the writer rather than bad input.

pub fn put_u16(&mut self, value: u16)

pub fn set_u16(&mut self, offset: usize, value: u16)

Overwrite a field already placed. Panics if it does not fit, which would be a bug in the writer rather than bad input.

pub fn put_u32(&mut self, value: u32)

pub fn set_u32(&mut self, offset: usize, value: u32)

Overwrite a field already placed. Panics if it does not fit, which would be a bug in the writer rather than bad input.

pub fn put_i32(&mut self, value: i32)

pub fn set_i32(&mut self, offset: usize, value: i32)

Overwrite a field already placed. Panics if it does not fit, which would be a bug in the writer rather than bad input.

pub fn put_u64(&mut self, value: u64)

pub fn set_u64(&mut self, offset: usize, value: u64)

Overwrite a field already placed. Panics if it does not fit, which would be a bug in the writer rather than bad input.

pub fn put_i64(&mut self, value: i64)

pub fn set_i64(&mut self, offset: usize, value: i64)

Overwrite a field already placed. Panics if it does not fit, which would be a bug in the writer rather than bad input.

pub fn put_f32(&mut self, value: f32)

pub fn set_f32(&mut self, offset: usize, value: f32)

Overwrite a field already placed. Panics if it does not fit, which would be a bug in the writer rather than bad input.

pub fn put_f64(&mut self, value: f64)

pub fn set_f64(&mut self, offset: usize, value: f64)

Overwrite a field already placed. Panics if it does not fit, which would be a bug in the writer rather than bad input.
