Enum MetadataCommandError 

#[non_exhaustive]
pub enum MetadataCommandError {
    NotFound {
        stdout: String,
    },
    Io(Error),
    Json(Error),
    ScarbError {
        stdout: String,
        stderr: String,
    },
}

Error thrown while trying to read scarb metadata.

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.

NotFound

Fields

stdout: String

Captured standard output if any.

Io(Error)

Failed to read scarb metadata output.

Json(Error)

Failed to deserialize scarb metadata output.

ScarbError

Error during execution of scarb metadata.

Fields

stderr: String

Implementations

impl MetadataCommandError

pub const fn did_not_found(&self) -> bool

Check if this is MetadataCommandError::NotFound.

Trait Implementations

impl Debug for MetadataCommandError

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

Formats the value using the given formatter.

impl Display for MetadataCommandError

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

impl Error for MetadataCommandError

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.
