Struct ModuleDiagnostic 

pub struct ModuleDiagnostic {
    pub message: String,
    pub labels: Vec<SourceLabel>,
    pub cause: Option<ModuleCause>,
}

Owns a module error message and all sources needed by its labels.

let diagnostic = adam_lang::ModuleDiagnostic {
    message: "invalid native use".into(),
    labels: vec![adam_lang::SourceLabel { location: None, label: "native".into() }],
    cause: None,
};
assert!(diagnostic.labels[0].location.is_none());

Fields

message: String

Explains the failed module operation.

labels: Vec<SourceLabel>

Identifies implicated definitions and uses in diagnostic order.

cause: Option<ModuleCause>

Retains an underlying construction error without replacing it with display text.

Trait Implementations

impl Clone for ModuleDiagnostic

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModuleDiagnostic

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

Formats the value using the given formatter.

impl Display for ModuleDiagnostic

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

Formats the primary diagnostic message without rendering source labels.

• Complexity: O(m) message bytes.

impl Eq for ModuleDiagnostic

impl Error for ModuleDiagnostic

fn source(&self) -> Option<&(dyn Error + 'static)>

Borrows the retained original error, if this diagnostic wraps a construction failure.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ModuleDiagnostic

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

Equality operator ==.

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

Inequality operator !=.
