Types 6
aliastoElementType(E : E[]) = E
converts slice types to their element type, preserves anything else
aliastoElementType(S) = S
aliastoElementType(alias op) = op
aliastoVecType(E : E[]) = vec!E
converts slice types to their element type, preserves anything else
aliastoVecType(S) = vec!S
aliastoVecType(alias op) = op
Functions 6
fn
T[] arrayOp(T : T[], Args...)(T[] res, Filter!(isType, Args) args) @trusted Perform array (vector) operations and store the result in `res`. Operand types and operations are passed as template arguments in Reverse Polish * Notation (RPN).fn
bool isBinaryAssignOp(string op)fn
string toString(size_t num)fn
bool contains(T)(const scope T[] ary, const scope T[] vals...)Templates 4
tmpltypeCheck(bool fail, T, Args...)
Check whether operations on operand types are supported. This template recursively reduces the expression tree and determines intermediate types. Type checking is done here rather than in the compiler to provide more detailed error messages.
Parameters
fail | whether to fail (static assert) with a human-friendly error message |
T | type of result |
Args | operand types and operations in RPN |
Returns
The resulting type of the expression
See Also
tmpltypeCheck(bool fail, T, ResultType)
ditto
tmplnot(alias tmlp)
tmplstaticIndexOf(alias pred, haystack...)
Find element in haystack for which pred is true.
Parameters
pred | the template predicate |
haystack | elements to search |
Returns
The first index for which
pred!haystack[index] is true or -1.
