Enum TargetError 

pub enum TargetError {
    NotFound,
    OutOfBounds,
    InvalidPosition {
        line: usize,
        col: Option<usize>,
    },
    InvalidPattern(String),
}

Errors that can occur when resolving a target to a rope index.

Variants

NotFound

The target was not found in the rope.

OutOfBounds

The target index is out of bounds.

InvalidPosition

The target position is invalid (e.g., line or column exceeds rope bounds).

Fields

line: usize

The line number that was invalid.

col: Option<usize>

The column number that was invalid (if applicable).

InvalidPattern(String)

Available on crate feature regex only.

The regex pattern failed to compile.

Trait Implementations

impl Clone for TargetError

fn clone(&self) -> TargetError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TargetError

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

Formats the value using the given formatter.

impl Display for TargetError

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

Formats the value using the given formatter.

impl Error for TargetError

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<TargetError> for BoundaryError

fn from(err: TargetError) -> Self

Converts to this type from the input type.

impl From<TargetError> for PatchError

fn from(e: TargetError) -> Self

Converts to this type from the input type.

impl From<TargetError> for SnippetError

fn from(err: TargetError) -> Self

Converts to this type from the input type.

impl PartialEq for TargetError

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