Struct ViewRefusal 

pub struct ViewRefusal { /* private fields */ }

One or more diagnostics, gathered as a refusal.

A refusal renders every diagnostic through crate::error::render_diagnostics, the one renderer tix link and tix parent set already share, so a user who learned one refusal format does not have to learn a second.

Implementations

impl ViewRefusal

pub fn from_diagnostics(diagnostics: Vec<ViewDiagnostic>) -> Self

Gather a non-empty diagnostic set.

Panics

Panics on an empty set: a refusal with no diagnostic cannot explain itself, and the callers that build one always have at least one reason.

pub fn from_diagnostic(diagnostic: ViewDiagnostic) -> Self

Refuse with one diagnostic.

pub fn diagnostics(&self) -> &[ViewDiagnostic]

Every diagnostic, in the order the operation produced them.

pub fn kind(&self) -> ViewDiagnosticKind

The first diagnostic’s kind — what a surface switches on for one line.

pub fn message(&self) -> &str

The first diagnostic’s message.

pub fn render(&self) -> String

All diagnostics as one line, through the shared renderer.

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
