Struct UnknownTypeKeyword 

#[non_exhaustive]
pub struct UnknownTypeKeyword {
    pub keyword: String,
}

Error returned by type_keyword_to_kind when the supplied keyword is not a recognized magic type keyword.

This is a tight, structured error surfaced from a pure mapping function that has no access to line-number context. Callers that do have line context (e.g. the grammar layer wrapping a higher-level parse) can convert it into a richer crate::error::ParseError variant if needed. The struct is #[non_exhaustive] so future fields (e.g. suggested alternatives) can be added without a major version bump.

Examples

use libmagic_rs::parser::types::{type_keyword_to_kind, UnknownTypeKeyword};

let err = type_keyword_to_kind("notarealtype").unwrap_err();
assert_eq!(err.keyword, "notarealtype");

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

keyword: String

The keyword string that was not recognized.

Trait Implementations

impl Clone for UnknownTypeKeyword

fn clone(&self) -> UnknownTypeKeyword

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnknownTypeKeyword

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

Formats the value using the given formatter.

impl Display for UnknownTypeKeyword

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

Formats the value using the given formatter.

impl Error for UnknownTypeKeyword

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 PartialEq for UnknownTypeKeyword

fn eq(&self, other: &UnknownTypeKeyword) -> 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.
