Source

fn try_as_i128(&self) -> Result<i128, TryTypeError>

Tries to represent the value as a i128

§Errors

if the requested type doesn’t match the actual type

Source

fn try_as_i64(&self) -> Result<i64, TryTypeError>

Tries to represent the value as an i64

§Errors

if the requested type doesn’t match the actual type

Source

fn try_as_i32(&self) -> Result<i32, TryTypeError>

Tries to represent the value as an i32

§Errors

if the requested type doesn’t match the actual type

Source

fn try_as_i16(&self) -> Result<i16, TryTypeError>

Tries to represent the value as an i16

§Errors

if the requested type doesn’t match the actual type

Source

fn try_as_i8(&self) -> Result<i8, TryTypeError>

Tries to represent the value as an i8

§Errors
