Trait AttributeValue

pub trait AttributeValue {
    // Required method
    fn write_attribute_value(self, w: &mut impl Write) -> Result;

    // Provided method
    fn is_unit(&self) -> bool { ... }
}

Represents a value of an attribute.

Required Methods

fn write_attribute_value(self, w: &mut impl Write) -> Result

Writes the attribute value to w.

Arguments

• w - The writer to write to.

Provided Methods

fn is_unit(&self) -> bool

Tells whether the attribute value is a unit value, meaning that it is not written.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
