Enum ConfigError 

pub enum ConfigError {
    NotFound {
        path: String,
        field: String,
    },
    TypeMismatch {
        path: String,
        field: String,
        stored: &'static str,
        requested: &'static str,
    },
}

Why a get failed. SystemVerilog collapses all of these into return 0 and leaves your variable untouched; naming them is the point.

Variants

NotFound

No entry matched the resolved path and field. Covers “never set”, “path does not match” and “field misspelled” — indistinguishable to any database addressed by strings, which is why ch28 exists.

Fields

path: String

field: String

TypeMismatch

An entry was found, but it holds another type. Only reportable because the type is not part of the key (D65).

Fields

path: String

field: String

stored: &'static str

requested: &'static str

Implementations

impl ConfigError

pub fn kind(&self) -> &'static str

Stable, machine-readable cause for #[rustdv::test(expect_error=…)].

Trait Implementations

impl Clone for ConfigError

fn clone(&self) -> ConfigError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigError

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

Formats the value using the given formatter.

impl Display for ConfigError

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

Formats the value using the given formatter.

impl Eq for ConfigError

impl Error for ConfigError

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<ConfigError> for TestError

Configuration failures keep their cause, so ? in a test body still lets expect_error distinguish “nothing was set” from “wrong type”.

fn from(e: ConfigError) -> Self

Converts to this type from the input type.

impl From<ConfigError> for SeqError

fn from(e: ConfigError) -> SeqError

Converts to this type from the input type.

impl PartialEq for ConfigError

fn eq(&self, other: &ConfigError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
