Enum Error 

pub enum Error {
    App {
        message: String,
    },
    Core(Error),
    TomlDeserialize {
        context: String,
        source: Error,
    },
    TomlSerialize {
        context: String,
        source: Error,
    },
}

Error types for the maps crate. Allows to handle app errors and wrapped external errors in a unified way.

Variants

App

A maps-internal and application-specific error.

Fields

message: String

Core(Error)

Error from maps_io_ros (I/O, YAML parsing, etc.)

TomlDeserialize

TOML deserialization error with additional context.

Fields

context: String

source: Error

TomlSerialize

TOML serialization error with additional context.

Fields

context: String

source: Error

Implementations

impl Error

pub fn app(message: impl ToString) -> Self

Create a new app-related error with a full error message.

pub fn toml_deserialize(context: impl ToString, source: Error) -> Self

Wrap a toml::de::Error with additional context message.

pub fn toml_serialize(context: impl ToString, source: Error) -> Self

Wrap a toml::ser::Error with additional context message.

pub fn io(context: impl ToString, source: Error) -> Self

Create I/O errors by delegating to maps_io_ros

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
