Enum SpaceError 

pub enum SpaceError {
    Io {
        path: String,
        source: Error,
    },
    Parse {
        path: String,
        source: Box<Error>,
    },
    Invalid(String),
    Constraint {
        expr: String,
        reason: String,
    },
}

What can go wrong loading a spec or enumerating its space.

Variants

Io

kernel.toml could not be read.

Fields

path: String

The file that could not be read.

source: Error

The underlying I/O failure.

Parse

kernel.toml is not valid TOML.

Fields

path: String

The file that would not parse.

source: Box<Error>

The TOML error, boxed because it is large and this variant is rare.

Invalid(String)

The TOML parsed but does not describe a usable space: a bad dimension name, an empty or duplicated value list, a block axis above the CUDA limit, or no dimensions at all.

Constraint

A [constraints] expression could not be parsed or evaluated — including arithmetic that would overflow or divide by zero, which is an error rather than a verdict.

Fields

expr: String

The expression as written in kernel.toml.

reason: String

What was wrong with it.

Trait Implementations

impl Debug for SpaceError

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

Formats the value using the given formatter.

impl Display for SpaceError

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

Formats the value using the given formatter.

impl Error for SpaceError

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.
