Enum ScaffoldError 

pub enum ScaffoldError {
    Parse(String),
    UnknownValue {
        target: String,
        field: String,
        value: String,
        options: Vec<&'static str>,
    },
    NotConfigurable {
        target: String,
        field: String,
        reason: &'static str,
    },
}

An error parsing or validating the bock.project scaffolding config.

Validation errors carry the offending field, value, target, and the list of documented options for that target (§20.6.2) so the build driver can render a message that points the user at the valid choices.

Variants

Parse(String)

The document was not valid TOML, or a config field had the wrong type.

UnknownValue

A config field was set to a value outside the documented options.

Fields

target: String

Target id ("js", "python", …).

field: String

Config field name ("test_framework", "formatter", "linter", "package_manager").

value: String

The unsupported value the user supplied.

options: Vec<&'static str>

Documented valid options for this field on this target (§20.6.2).

NotConfigurable

A field was supplied for a target where it is not user-configurable (e.g. Rust/Go formatter/test_framework, which are universal).

Fields

target: String

Target id.

field: String

Config field name.

reason: &'static str

Why it is not configurable, for the error message.

Trait Implementations

impl Clone for ScaffoldError

fn clone(&self) -> ScaffoldError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScaffoldError

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

Formats the value using the given formatter.

impl Display for ScaffoldError

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

Formats the value using the given formatter.

impl Eq for ScaffoldError

impl Error for ScaffoldError

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 PartialEq for ScaffoldError

fn eq(&self, other: &ScaffoldError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
