Enum RequireParseError 

pub enum RequireParseError {
    Empty,
    Tag(CapabilityTagError),
    NumericParse {
        key: String,
        value: String,
    },
    InvalidKey {
        key: String,
    },
    InvalidAxis {
        axis: String,
    },
}

Errors raised by the require! family of macros at parse time. All are programmer errors — the macros panic with these messages so misuse fails loudly at first run.

Variants

Empty

Empty input passed to a require*! macro.

Tag(CapabilityTagError)

Wrapped CapabilityTagError from tag parsing (e.g. user attempted to emit a reserved-prefix tag).

NumericParse

Numeric comparison’s right-hand side did not parse to f64. Carries the original lhs / rhs spelling for diagnostics.

Fields

key: String

Tag-key portion of the failed comparison (hardware.gpu.vram_gb).

value: String

Right-hand-side spelling that failed to parse (twenty-four).

InvalidKey

Tag key (<axis>.<key>) couldn’t be parsed (missing dot or unknown axis prefix).

Fields

key: String

Offending key spelling.

InvalidAxis

Unknown axis literal passed to require_axis!.

Fields

axis: String

Offending axis spelling.

Trait Implementations

impl Debug for RequireParseError

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

Formats the value using the given formatter.

impl Display for RequireParseError

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

Formats the value using the given formatter.

impl Error for RequireParseError

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<CapabilityTagError> for RequireParseError

fn from(source: CapabilityTagError) -> Self

Converts to this type from the input type.
