Enum GraphQueryError

#[non_exhaustive]
pub enum GraphQueryError {
    InvalidPattern {
        context: &'static str,
        source: PatternError,
    },
    ZeroFolderDepth,
    EmptyCollapseReplacement,
    EmptyTitle,
    EmptyCollapsedNode {
        node: String,
    },
}

Invalid graph query input or a collapse that cannot produce a report node.

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.

InvalidPattern

A focus, traversal, or collapse pattern could not be compiled.

Fields

context: &'static str

The query modifier that owns the pattern.

source: PatternError

The shared pattern compiler’s diagnostic.

ZeroFolderDepth

Folder collapsing requires at least one path component.

EmptyCollapseReplacement

Pattern collapsing needs a non-empty replacement expression.

EmptyTitle

Snapshot titles must contain visible text.

EmptyCollapsedNode

A capture replacement erased a selected node label.

Fields

node: String

The original normalized graph identifier.

Trait Implementations

impl Clone for GraphQueryError

fn clone(&self) -> GraphQueryError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GraphQueryError

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

Formats the value using the given formatter.

impl Display for GraphQueryError

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

Formats the value using the given formatter.

impl Error for GraphQueryError

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.
