Implementations

impl DiagnosticMessage

pub fn render(&self) -> String

Renders DiagnosticMessage by interpolating all dynamic values into a template

Trait Implementations

impl Clone for DiagnosticMessage

fn clone(&self) -> DiagnosticMessage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DiagnosticMessage

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for DiagnosticMessage

impl PartialEq for DiagnosticMessage

fn eq(&self, other: &DiagnosticMessage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for DiagnosticMessage
