Enum ValidationOutcome 

#[non_exhaustive]
pub enum ValidationOutcome {
    Success(Vec<Diagnostic>),
    IoError(FileError),
    Skipped,
}

Outcome of validating a single file.

Returned by crate::validate_file and crate::validate_file_with_registry. The Ok path of LintResult<ValidationOutcome> covers all per-file situations - successful validation, I/O errors, and skipped files - while the Err path is reserved for config-level errors (e.g. invalid exclude patterns, too many files).

Use into_diagnostics() for a quick migration path from the previous Vec<Diagnostic> return type.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Success(Vec<Diagnostic>)

Validation ran successfully. The contained diagnostics may be empty (no issues found) or non-empty (issues found).

IoError(FileError)

The file could not be read due to an I/O or filesystem error.

Skipped

The file type is unknown and no validation was performed.

Implementations

impl ValidationOutcome

pub fn is_success(&self) -> bool

Returns true if validation ran (regardless of whether diagnostics were found).

pub fn is_io_error(&self) -> bool

Returns true if the file could not be read.

pub fn is_skipped(&self) -> bool

Returns true if the file was skipped (unknown file type).

pub fn diagnostics(&self) -> &[Diagnostic]

Borrow the diagnostics from a successful validation.

Returns an empty slice for IoError and Skipped variants.

pub fn into_diagnostics(self) -> Vec<Diagnostic>

Consume the outcome and return the diagnostics.

• Success: returns the contained diagnostics.
• IoError: returns a single file::read diagnostic describing the error.
• Skipped: returns an empty Vec.

pub fn io_error(&self) -> Option<&FileError>

If this is an IoError, return a reference to the underlying FileError.

Trait Implementations

impl Debug for ValidationOutcome

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

Formats the value using the given formatter.
