Enum CodegenError 

pub enum CodegenError {
    Parse(Error),
    Validate(String),
    Io(Error),
    Pretty(String),
}

Errors that can occur while expanding the graph DSL into Rust code.

Variants

Parse(Error)

The DSL could not be parsed into a valid AST.

Validate(String)

The AST failed semantic validation (for example, non-contiguous indices, port bound violations, payload mismatches, or queue non-uniformity).

Io(Error)

I/O failure while reading or writing generated code.

Pretty(String)

Pretty-printing (token → formatted Rust source) failed.

Trait Implementations

impl Debug for CodegenError

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

Formats the value using the given formatter.

impl Display for CodegenError

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

Formats the value using the given formatter.

impl Error for CodegenError

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 CodegenError

fn from(source: Error) -> Self

Converts to this type from the input type.
