Required Methods§

Source

fn read_ue(&mut self, name: &'static str) -> Result<u32, BitReaderError>

Reads an unsigned Exp-Golomb-coded value, as defined in the H.264 spec.

Source

fn read_se(&mut self, name: &'static str) -> Result<i32, BitReaderError>

Reads a signed Exp-Golomb-coded value, as defined in the H.264 spec.

Source

fn read_bool(&mut self, name: &'static str) -> Result<bool, BitReaderError>

Reads a single bit, as in [crate::bitstream_io::read::BitRead::read_bool].

Source

fn read<U: Numeric>( &mut self, bit_count: u32, name: &'static str, ) -> Result<U, BitReaderError>

Reads an unsigned value from the bitstream with the given number of bytes, as in crate::bitstream_io::read::BitRead::read.

Source

fn read_to<V: Primitive>( &mut self, name: &'static str, ) -> Result<V, BitReaderError>

Reads a whole value from the bitstream whose size is equal to its byte size, as in crate::bitstream_io::read::BitRead::read_to.

Source

fn skip( &mut self, bit_count: u32, name: &'static str, ) -> Result<(), BitReaderError>

Skips the given number of bits in the bitstream, as in crate::bitstream_io::read::BitRead::skip.

Source

fn has_more_rbsp_data( &mut self, name: &'static str, ) -> Result<bool, BitReaderError>

Returns true if positioned before the RBSP trailing bits.

This matches the definition of more_rbsp_data() in Rec. ITU-T H.264 (03/2010) section 7.2.

Source

fn finish_rbsp(self) -> Result<(), BitReaderError>

Consumes the reader, returning error if it’s not positioned at the RBSP trailing bits.

Source

fn finish_sei_payload(self) -> Result<(), BitReaderError>

Consumes the reader, returning error if this sei_payload message is unfinished.

This is similar to finish_rbsp, but SEI payloads have no trailing bits if already byte-aligned.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
