Implementations§

source§

impl<'a> Val<'a>

source

pub fn as_bool(&self) -> Option<bool>

Returns the value if it is a boolean, otherwise None.

source

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

Represents the value as f64 if possible. Returns None otherwise.

source

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

Represents the value as f64 if possible. Returns None otherwise.

source

pub fn as_str(&self) -> Option<&'a str>

Returns the string if this value is a string, otherwise None.

source

pub fn as_uuid(&self) -> Option<Uuid>

Returns the UUID if this value is a UUID, otherwise None.
