Enum VarError 

#[non_exhaustive]
pub enum VarError {
    Name {
        name: String,
    },
    Reserved,
    Unknown {
        name: VarName,
        declared: Vec<VarName>,
    },
    Unanswered {
        questions: Vec<Question>,
    },
    Undeclared {
        path: RelPath,
        name: String,
        declared: Vec<VarName>,
    },
    Template {
        path: RelPath,
        reason: String,
    },
}

Why the layers’ variables cannot be answered or rendered.

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.

Name

A name is not an identifier.

Fields

name: String

The rejected input.

Reserved

A variable is named devset, which templates see the target’s profiles under.

Unknown

The target answers a variable no layer declares.

Fields

name: VarName

The answered name.

declared: Vec<VarName>

Every declared name.

Unanswered

The target has not answered these variables.

Fields

questions: Vec<Question>

One per variable.

Undeclared

A template uses a variable no profile declares.

Fields

path: RelPath

The template.

name: String

The variable.

declared: Vec<VarName>

Every declared name.

Template

A template cannot be read as text.

Fields

path: RelPath

The template.

reason: String

Why not.

Trait Implementations

impl Clone for VarError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarError

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

Formats the value using the given formatter.

impl Display for VarError

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

Formats the value using the given formatter.

impl Eq for VarError

impl Error for VarError

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<VarError> for Error

fn from(source: VarError) -> Self

Converts to this type from the input type.

impl PartialEq for VarError

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

Equality operator ==.

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

Inequality operator !=.
