Enum NameSpec 

pub enum NameSpec {
    Static(&'static str),
    DerivedFrom(&'static str),
    DerivedWithDefault {
        input_name: &'static str,
        default: &'static str,
    },
}

How the runtime name of an OutputSpec or ExtensionSpec is determined.

Static names are fixed at declaration time; derived names are looked up from a Type::Text input when the step runs, optionally falling back to a static default.

Variants

Static(&'static str)

A fixed name known at declaration time.

DerivedFrom(&'static str)

The name is read from the named input at runtime. The input must be declared on the operation with ty: Type::Text.

DerivedWithDefault

As for DerivedFrom, but falls back to default when the input is absent at runtime. The referenced input must be optional (required: false).

Fields

input_name: &'static str

The name of the input to read the output name from.

default: &'static str

The fallback name used when the input is absent.

Trait Implementations

impl Clone for NameSpec

fn clone(&self) -> NameSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NameSpec

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

Formats the value using the given formatter.

impl PartialEq for NameSpec

fn eq(&self, other: &NameSpec) -> 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.
