Struct BsvReader 

pub struct BsvReader<'a> { /* private fields */ }

A cursor-based reader for Bitcoin protocol binary data.

Wraps a byte slice and maintains a read position, providing methods to read fixed-size integers and VarInt values in little-endian order.

Implementations

impl<'a> BsvReader<'a>

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

Create a new reader over the given byte slice.

Arguments

• data - The byte slice to read from.

Returns

A BsvReader positioned at the start of the data.

pub fn read_bytes(&mut self, n: usize) -> Result<&'a [u8], PrimitivesError>

Read n bytes and advance the position.

Arguments

• n - Number of bytes to read.

Returns

A byte slice of length n, or an error if insufficient data remains.

pub fn read_u8(&mut self) -> Result<u8, PrimitivesError>

Read a single byte and advance the position.

Returns

The byte value, or an error if no data remains.

pub fn read_u16_le(&mut self) -> Result<u16, PrimitivesError>

Read a little-endian u16 and advance the position by 2 bytes.

Returns

The decoded u16, or an error if insufficient data.

pub fn read_u32_le(&mut self) -> Result<u32, PrimitivesError>

Read a little-endian u32 and advance the position by 4 bytes.

Returns

The decoded u32, or an error if insufficient data.

pub fn read_u64_le(&mut self) -> Result<u64, PrimitivesError>

Read a little-endian u64 and advance the position by 8 bytes.

Returns

The decoded u64, or an error if insufficient data.

pub fn read_varint(&mut self) -> Result<VarInt, PrimitivesError>

Read a VarInt and advance the position accordingly.

Returns

The decoded VarInt, or an error if insufficient data.

pub fn remaining(&self) -> usize

Return the number of bytes remaining.

Returns

The count of unread bytes.
