Enum BlockError 

pub enum BlockError {
    PathNotFound {
        path: Vec<usize>,
    },
    IndexOutOfRange {
        parent: Vec<usize>,
        index: usize,
    },
    NoParent,
    NoPreviousSibling {
        path: Vec<usize>,
    },
    InvalidRange {
        parent: Vec<usize>,
        start: usize,
        end: usize,
    },
    Range(RangeError),
}

Why a block-structural operation could not be applied.

Variants

PathNotFound

No node exists at the given path.

Fields

path: Vec<usize>

The unresolved path.

IndexOutOfRange

A child index is out of range for the parent.

Fields

parent: Vec<usize>

The parent path.

index: usize

The offending index.

NoParent

The operation needs a parent (and sometimes a grandparent) the path lacks.

NoPreviousSibling

join_blocks was asked to merge index 0 (no previous sibling).

Fields

path: Vec<usize>

The path that has no previous sibling.

InvalidRange

A BlockRange is inverted or extends past the parent’s children.

Fields

parent: Vec<usize>

The parent path.

start: usize

Start index.

end: usize

End index.

Range(RangeError)

A mid-text split boundary could not be resolved (forwarded from range).

Trait Implementations

impl Clone for BlockError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockError

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

Formats the value using the given formatter.

impl Display for BlockError

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

Formats the value using the given formatter.

impl Eq for BlockError

impl Error for BlockError

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<BlockError> for PosEditError

fn from(e: BlockError) -> Self

Converts to this type from the input type.

impl From<RangeError> for BlockError

fn from(e: RangeError) -> Self

Converts to this type from the input type.

impl PartialEq for BlockError

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

Equality operator ==.

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

Inequality operator !=.
