}

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

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

Required Methods

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

where T: SeekNum,

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

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

where T: SeekNum,

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

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.
