Struct rmpv::Integer

pub struct Integer { /* fields omitted */ }

Represents a MessagePack integer, whether signed or unsigned.

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

Methods

impl Integer

pub fn is_i64(&self) -> bool

Returns true if the integer can be represented as i64.

pub fn is_u64(&self) -> bool

Returns true if the integer can be represented as u64.

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

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

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

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

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

Returns the integer represented as f64 if possible, or else None.
