}

Trait implemented for numeric types which can be used with the StreamCipherSeek trait.

This trait is implemented for primitive numeric types, i.e. i/u8, u16, u32, u64, u128, usize, and i32. It is not intended to be implemented in third-party crates.

Required Methods

fn from_block_byte<T: SeekNum>(
    block: T,
    byte: u8,
    bs: u8
) -> Result<Self, OverflowError>

Try to get position for block number block, byte position inside block byte, and block size bs.

fn to_block_byte<T: SeekNum>(self, bs: u8) -> Result<(T, u8), OverflowError>

Try to get block number and bytes position for given block size bs.
