Trait CborValueExt 

pub trait CborValueExt {
    // Required methods
    fn as_str(&self) -> Option<&str>;
    fn as_i64(&self) -> Option<i64>;
    fn as_u64(&self) -> Option<u64>;
    fn as_f64(&self) -> Option<f64>;
    fn get(&self, key: &str) -> Option<&Value>;
    fn get_mut(&mut self, key: &str) -> Option<&mut Value>;
}

Required Methods

fn as_str(&self) -> Option<&str>

Borrow the inner string if this is a Text value.

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

Try to extract an i64. Returns None if the value is not an integer or doesn’t fit.

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

Try to extract a u64. Returns None if the value is not an integer or doesn’t fit.

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

Borrow the inner f64 if this is a Float value.

fn get(&self, key: &str) -> Option<&Value>

Look up a value in a Map by string key. Returns None if the value isn’t a map or the key isn’t present.

fn get_mut(&mut self, key: &str) -> Option<&mut Value>

Same as get, but returns a mutable reference.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
