Struct rmpv::Integer

source ·
pub struct Integer { /* private fields */ }
Expand description

Represents a MessagePack integer, whether signed or unsigned.

A Value or ValueRef that contains integer can be constructed using From trait.

Implementations§

source§

impl Integer

source

pub fn is_i64(&self) -> bool

Returns true if the integer can be represented as u64.

source

pub fn as_i64(&self) -> Option<i64>

Returns the integer represented as i64 if possible, or else None.

source

pub fn as_u64(&self) -> Option<u64>

Returns the integer represented as u64 if possible, or else None.

source

pub fn as_f64(&self) -> Option<f64>
