Enum grep_searcher::ConfigError

#[non_exhaustive]
pub enum ConfigError {
    SearchUnavailable,
    MismatchedLineTerminators {
        matcher: LineTerminator,
        searcher: LineTerminator,
    },
    UnknownEncoding {
        label: Vec<u8>,
    },
}

An error that can occur when building a searcher.

This error occurs when a non-sensical configuration is present when trying to construct a Searcher from a SearcherBuilder.

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.

SearchUnavailable

Indicates that the heap limit configuration prevents all possible search strategies from being used. For example, if the heap limit is set to 0 and memory map searching is disabled or unavailable.

MismatchedLineTerminators

Fields

matcher: LineTerminator

The matcher’s line terminator.

searcher: LineTerminator

The searcher’s line terminator.

Occurs when a matcher reports a line terminator that is different than the one configured in the searcher.

UnknownEncoding

Fields

label: Vec<u8>

The provided encoding label that could not be found.

Occurs when no encoding could be found for a particular label.

Trait Implementations

impl Clone for ConfigError

fn clone(&self) -> ConfigError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigError

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

Formats the value using the given formatter.

impl Display for ConfigError

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

Formats the value using the given formatter.

impl Error for ConfigError

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

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<ConfigError> for ConfigError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
