Struct ModuleCause 

pub struct ModuleCause(/* private fields */);

Shares an immutable diagnostic cause with identity-based equality.

Clones retain the same error identity; separately constructed causes remain distinct. See ModuleDiagnostic.

Implementations

impl ModuleCause

pub fn new(error: impl Error + 'static) -> Self

Retains a concrete error, including non-Send native template ownership handles.

Examples

let cause = adam_lang::source_map::ModuleCause::new(std::io::Error::other("failure"));
assert_eq!(cause, cause.clone());

pub fn as_error(&self) -> &(dyn Error + 'static)

Borrows the original error for source traversal and concrete downcasting.

Examples

let cause = adam_lang::source_map::ModuleCause::new(std::io::Error::other("failure"));
assert!(cause.as_error().is::<std::io::Error>());
