Implementations

impl Diagnostic

pub fn error(
    file_id: usize,
    code: impl Into<String>,
    title: impl Into<String>
) -> Diagnostic

Creates a new Diagnostic with the Error severity.

pub fn warning(
    file_id: usize,
    code: impl Into<String>,
    title: impl Into<String>
) -> Diagnostic

Creates a new Diagnostic with the Warning severity.

pub fn help(
    file_id: usize,
    code: impl Into<String>,
    title: impl Into<String>
) -> Diagnostic

Creates a new Diagnostic with the Help severity.

pub fn note(
    file_id: usize,
    code: impl Into<String>,
    title: impl Into<String>
) -> Diagnostic

Creates a new Diagnostic with the Note severity.

pub fn new(
    file_id: usize,
    severity: Severity,
    title: impl Into<String>
) -> Diagnostic

Creates a new Diagnostic that will be used in a builder-like way to modify labels, and suggestions.

pub fn new_with_code(
    file_id: usize,
    severity: Severity,
    title: impl Into<String>,
    code: Option<String>
) -> Diagnostic

Creates a new Diagnostic with an error code that will be used in a builder-like way to modify labels, and suggestions.

pub fn severity(self, severity: Severity) -> Diagnostic

Overwrites the severity of this diagnostic.

pub fn deprecated(self) -> Diagnostic

Marks this diagnostic as deprecated code, which will be displayed in the language server.

This does not have any influence on the diagnostic rendering.

pub fn unnecessary(self) -> Diagnostic

Marks this diagnostic as unnecessary code, which will be displayed in the language server.

This does not have any influence on the diagnostic rendering.

pub fn label_in_file(
    self,
    severity: Severity,
    span: FileSpan,
    msg: String
) -> Diagnostic

Attaches a label to this Diagnostic, that will point to another file that is provided.

pub fn label(
    self,
    severity: Severity,
    span: impl Span,
    msg: impl Into<String>
) -> Diagnostic

Attaches a label to this Diagnostic.

The given span has to be in the file that was provided while creating this Diagnostic.

pub fn primary(self, span: impl Span, msg: impl Into<String>) -> Diagnostic

Attaches a primary label to this Diagnostic.

pub fn secondary(self, span: impl Span, msg: impl Into<String>) -> Diagnostic

Attaches a secondary label to this Diagnostic.

pub fn suggestion_in_file(
    self,
    span: impl Span,
    msg: &str,
    suggestion: impl Into<String>,
    applicability: Applicability,
    file: usize
) -> Diagnostic

Prints out a message that suggests a possible solution, that is in another file as this Diagnostic, to the error.

If the message plus the suggestion is longer than 25 chars, the suggestion is displayed as a new children of this Diagnostic, otherwise it will be inlined with the other labels.

A suggestion is displayed like:

try adding a `;`: console.log();

or in a separate multiline suggestion

The message should not contain the : because it’s added automatically. The suggestion will automatically be wrapped inside two backticks.

pub fn suggestion(
    self,
    span: impl Span,
    msg: &str,
    suggestion: impl Into<String>,
    applicability: Applicability
) -> Diagnostic

Prints out a message that suggests a possible solution to the error.

If the message plus the suggestion is longer than 25 chars, the suggestion is displayed as a new children of this Diagnostic, otherwise it will be inlined with the other labels.

A suggestion is displayed like:

try adding a `;`: console.log();

or in a separate multiline suggestion

The message should not contain the : because it’s added automatically. The suggestion will automatically be wrapped inside two backticks.

pub fn suggestion_full(
    self,
    span: impl Span,
    msg: &str,
    suggestion: impl Into<String>,
    applicability: Applicability
) -> Diagnostic

Add a suggestion which is always shown in the Full style.

pub fn suggestion_inline(
    self,
    span: impl Span,
    msg: &str,
    suggestion: impl Into<String>,
    applicability: Applicability
) -> Diagnostic

Add a suggestion which is always shown in the Inline style.

pub fn suggestion_no_code(
    self,
    span: impl Span,
    msg: &str,
    applicability: Applicability
) -> Diagnostic

Add a suggestion which does not have a suggestion code.

pub fn indel_suggestion(
    self,
    indels: impl IntoIterator<Item = Indel>,
    span: impl Span,
    msg: &str,
    applicability: Applicability
) -> Diagnostic

pub fn suggestion_with_labels(
    self,
    span: impl Span,
    msg: &str,
    suggestion: impl Into<String>,
    applicability: Applicability,
    labels: impl IntoIterator<Item = impl Span>
) -> Diagnostic

Add a suggestion with info labels which point to places in the suggestion.

The label ranges are relative to the start of the span, not relative to the original code

pub fn suggestion_with_src_labels(
    self,
    span: impl Span,
    msg: &str,
    suggestion: impl Into<String>,
    applicability: Applicability,
    labels: impl IntoIterator<Item = impl Span>
) -> Diagnostic

Add a suggestion with info labels which point to places in the suggestion.

The label ranges are relative to the source code, not relative to the original code

pub fn footer(self, severity: Severity, msg: impl Into<String>) -> Diagnostic

Adds a footer to this Diagnostic, which will be displayed under the actual error.

pub fn footer_help(self, msg: impl Into<String>) -> Diagnostic

Adds a footer to this Diagnostic, with the Help severity.

pub fn footer_note(self, msg: impl Into<String>) -> Diagnostic

Adds a footer to this Diagnostic, with the Note severity.
