Implementations

impl ExtensionValue

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

If the ExtensionValue is a String, returns the associated str. Returns None otherwise.

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

If the ExtensionValue is a Boolean, returns the associated bool. Returns None otherwise.

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

If the ExtensionValue is a Number and an i64, returns the associated i64. Returns None otherwise.

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

If the ExtensionValue is a Number and an f64, returns the associated f64. Returns None otherwise.
