Enum Refusal 

pub enum Refusal {
    Broken,
    NotAName,
    Imported(String),
    NotAnIdentifier(String),
    Taken(String),
    Unaccounted(String),
    WouldNotCompile {
        code: String,
        message: String,
    },
    WouldStopBeingAnApplication,
}

Why a rename will not happen.

A variant per reason rather than one string, because the caller renders them: a language server puts them in an error response and a browser tab puts them beside the box somebody typed in.

Variants

Broken

The document does not currently compile, so there is no program to rename in.

NotAName

There is no name under the caret.

Imported(String)

The name is declared in another module, and this editor is not showing that file.

NotAnIdentifier(String)

The new name is not one the lexer would read as an identifier.

Taken(String)

Something in this document is already written under the new name.

Unaccounted(String)

The name is used in a way this document’s analysis cannot account for — see Editor::occurrences.

WouldNotCompile

The edit was made and the result does not compile.

Fields

code: String

message: String

WouldStopBeingAnApplication

The edit was made, the result compiles, and it is no longer an application.

Implementations

impl Refusal

pub fn message(&self) -> String

The sentence a person reads, in the terms they typed in.

Trait Implementations

impl Clone for Refusal

fn clone(&self) -> Refusal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Refusal

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

Formats the value using the given formatter.

impl PartialEq for Refusal

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