Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ReadDar

The .dar could not be read.

Fields

path: PathBuf

The DAR that could not be read.

source: DarError

The underlying container error.

DecodeDar

The .dar could not be decoded.

Fields

path: PathBuf

The DAR that could not be decoded.

source: DecodeError

The underlying decode error.

EmptyDar

The archive held no Daml-LF packages to generate from.

Fields

path: PathBuf

The offending archive.

InvalidCrateName

The requested crate name is not a valid Cargo package name.

Fields

name: String

The rejected name.

InvalidCrateVersion

The DAR’s package version is not usable as a Cargo version.

It is refused rather than sanitised because the version reaches the generated Cargo.toml, and a DAR is not necessarily something the caller wrote.

Fields

version: String

The rejected version, as the DAR declared it.

InvalidRuntimeRequirement

The canton-daml version requirement is not one Cargo can parse.

Fields

requirement: String

The rejected requirement.

WouldClobber

An output file exists and was not written by this tool.

Fields

path: PathBuf

The file that would have been overwritten.

Codegen(CodegenError)

The generated tokens were not valid Rust — a bug in this crate.

Write

Writing the output crate failed.

Fields

path: PathBuf

The path being written.

source: Error

The underlying I/O error.

Trait Implementations

impl Debug for GenerateError

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

Formats the value using the given formatter.

impl Display for GenerateError

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

Formats the value using the given formatter.

impl Error for GenerateError

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<CodegenError> for GenerateError

fn from(source: CodegenError) -> Self

Converts to this type from the input type.
