Struct DescriptorError 

pub struct DescriptorError { /* private fields */ }

An error that may occur while creating a DescriptorPool.

Implementations

impl DescriptorError

pub fn file(&self) -> Option<&str>

The primary file in which this error occurred.

pub fn line(&self) -> Option<usize>

The 0-based line number at which this error occurred, if available.

This field may be None if the error is not associated with a particular source location, or the source_code_info field was not populated for the input file.

pub fn column(&self) -> Option<usize>

The 0-based column number at which this error occurred, if available.

This field may be None if the error is not associated with a particular source location, or the source_code_info field was not populated for the input file.

pub fn path(&self) -> Option<&[i32]>

Gets the path where this error occurred in the FileDescriptorProto, if available.

See path for more details on the structure of the path.

pub fn with_source_code(self, source: &str) -> Self

Available on crate feature miette only.

Provide source code information for this error.

The source should correspond to the contents of file().

Trait Implementations

impl Debug for DescriptorError

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

Formats the value using the given formatter.

impl Diagnostic for DescriptorError

Available on crate feature miette only.

fn code<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

Unique diagnostic code that can be used to look up more information about this Diagnostic. Ideally also globally unique, and documented in the toplevel crate’s documentation for easy searching. Rust path format (foo::bar::baz) is recommended, but more classic codes like E0123 or enums will work just fine.

fn severity(&self) -> Option<Severity>

Diagnostic severity. This may be used by ReportHandlers to change the display format of this diagnostic.

fn help<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

Additional help text related to this Diagnostic. Do you have any advice for the poor soul who’s just run into this issue?

fn url<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

URL to visit for a more detailed explanation/help about this Diagnostic.

fn source_code(&self) -> Option<&dyn SourceCode>

Source code to apply this Diagnostic’s Diagnostic::labels to.

fn labels(&self) -> Option<Box<dyn Iterator<Item = LabeledSpan> + '_>>

Labels to apply to this Diagnostic’s Diagnostic::source_code

fn related<'a>( &'a self, ) -> Option<Box<dyn Iterator<Item = &'a dyn Diagnostic> + 'a>>

Additional related Diagnostics.

fn diagnostic_source(&self) -> Option<&dyn Diagnostic>

The cause of the error.

impl Display for DescriptorError

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

Formats the value using the given formatter.

impl Error for DescriptorError

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.
