Implementations§

§

impl Integer

pub const fn is_zero(&self) -> bool

Returns true if the value contained is zero.

pub const fn as_i8(&self) -> Result<i8, Error>

Returns the contained value as an i8, or an error if the value is unable to fit.

pub const fn as_u8(&self) -> Result<u8, Error>

Returns the contained value as an u8, or an error if the value is unable to fit.

pub const fn as_i16(&self) -> Result<i16, Error>

Returns the contained value as an i16, or an error if the value is unable to fit.

pub const fn as_u16(&self) -> Result<u16, Error>

Returns the contained value as an u16, or an error if the value is unable to fit.

pub const fn as_i32(&self) -> Result<i32, Error>

Returns the contained value as an i32, or an error if the value is unable to fit.

pub const fn as_u32(&self) -> Result<u32, Error>

Returns the contained value as an u32, or an error if the value is unable to fit.

pub const fn as_i64(&self) -> Result<i64, Error>

Returns the contained value as an i64, or an error if the value is unable to fit.

pub const fn as_i128(&self) -> Result<i128, Error>

Returns the contained value as an i64, or an error if the value is unable to fit.

pub const fn as_u64(&self) -> Result<u64, Error>

Returns the contained value as an u64, or an error if the value is unable to fit.

pub const fn as_u128(&self) -> Result<u128, Error>

Returns the contained value as an u64, or an error if the value is unable to fit.

pub fn write_to<W>(&self, writer: W) -> Result<usize, Error>
where W: WriteBytesExt,

Writes this value using the smallest form possible.

pub fn read_from<R>( kind: Kind, byte_len: usize, reader: &mut R ) -> Result<Integer, Error>
where R: ReadBytesExt,

Reads an integer based on the atom header (kind and byte_len). byte_len should be the argument from the atom header directly.

pub fn as_f32(&self) -> Result<f32, Error>

Converts this integer to an f32, but only if it can be done without losing precision.

pub fn as_f64(&self) -> Result<f64, Error>

Converts this integer to an f64, but only if it can be done without losing precision.

pub fn as_float(&self) -> Result<Float, Error>

Converts this integer to an f64, but only if it can be done without losing precision.
