Enum NormalizeError 

pub enum NormalizeError {
    DuplicateAttr {
        path: String,
        first: u32,
        second: u32,
    },
    DuplicateFormal {
        name: String,
        at: u32,
    },
}

A parse-time rejection. Carries what is needed to render nix’s message.

nix has FIVE distinct reject messages, not one; this models the two that duplicate-attribute normalization produces. The other three (dynamic attributes in let/inherit, and the ${e} force-time collision) belong to their own layers.

Variants

DuplicateAttr

attribute '<dotted-path>' already defined at <pos>

Fields

path: String

The full dotted path, already quoted per showAttrPath rules.

first: u32

Byte offset of the FIRST definition.

second: u32

Byte offset of the offending one.

DuplicateFormal

duplicate formal function argument '<name>'

Fields

name: String

The repeated formal’s name.

at: u32

Byte offset to report.

Trait Implementations

impl Clone for NormalizeError

fn clone(&self) -> NormalizeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NormalizeError

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

Formats the value using the given formatter.

impl Eq for NormalizeError

impl Error for NormalizeError

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 NormalizeError

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

Equality operator ==.

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

Inequality operator !=.
