templateOr

Combines multiple templates with logical OR. So $(D_PSYMBOL templateOr) evaluates to Preds[0] || Preds[1] || Preds[2] and so on.

Empty Preds evaluates to $(D_KEYWORD false).

template templateOr (

Preds...

) if (

allSatisfy!(isTemplate, Preds)

) {

template templateOr(T...);

}

Members

Templates

templateOr template templateOr(T...): Undocumented in source.

Parameters

Preds: Template predicates.

Return Value

The constructed template.

Examples

alias isMutableOrInt = templateOr!(isIntegral, isMutable);
static assert(isMutableOrInt!int);
static assert(isMutableOrInt!(const int));
static assert(isMutableOrInt!float);
static assert(!isMutableOrInt!(const float));

alias alwaysFalse = templateOr!();
static assert(!alwaysFalse!int);

alias isIntegral = templateOr!(.isIntegral);
static assert(isIntegral!int);
static assert(isIntegral!(const int));
static assert(!isIntegral!float);
