Enum brane_ast::errors::LocationError

pub enum LocationError {
    IllegalLocation {
        range: TextRange,
    },
    OnNoLocation {
        range: TextRange,
        reasons: Vec<TextRange>,
    },
    NoLocation {
        range: TextRange,
        reasons: Vec<TextRange>,
    },
}

Defines errors that occur during location resolving.

Variants

IllegalLocation

A location was not a literal string.

Fields

range: TextRange

OnNoLocation

An On-structure combination already limited the locations too much.

Fields

range: TextRange

reasons: Vec<TextRange>

NoLocation

The usage of On-structures and/or annotations caused a function to never-ever be able to run.

Fields

range: TextRange

reasons: Vec<TextRange>

Implementations

impl LocationError

pub fn prettyprint(&self, file: impl AsRef<str>, source: impl AsRef<str>)

Prints the warning in a pretty way to stderr.

Arguments

• file: The ‘path’ of the file (or some other identifier) where the source text originates from.
• source: The source text to read the debug range from.

pub fn prettywrite( &self, writer: impl Write, file: impl AsRef<str>, source: impl AsRef<str>, ) -> Result<(), Error>

Prints the warning in a pretty way to the given Writer.

Arguments:

• writer: The Write-enabled object to write to.
• file: The ‘path’ of the file (or some other identifier) where the source text originates from.
• source: The source text to read the debug range from.

Errors

This function may error if we failed to write to the given writer.

Trait Implementations

impl Debug for LocationError

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

Formats the value using the given formatter.

impl Display for LocationError

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

Formats the value using the given formatter.

impl Error for LocationError

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

Returns the lower-level source of this error, if any.

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 From<LocationError> for AstError

fn from(err: LocationError) -> Self

Converts to this type from the input type.
