parse

std conv

Parses an enum type from a string representing an enum member name.

  1. auto parse(Source source)
  2. auto parse(Source s)
  3. auto parse(Source source, uint radix)
  4. auto parse(Source s)
    auto
    parse
    (
    Target
    Source
    Flag!"doCount" doCount = No.doCount
    )
    (
    ref Source s
    )
    if (
    is(Target == enum) &&
    isSomeString!Source
    &&
    !is(Source == enum)
    )
  5. auto parse(Source source)
  6. auto parse(Source s)
  7. auto parse(Source s)
  8. auto parse(Source s)
  9. auto parse(Source s, dchar lbracket, dchar rbracket, dchar comma)
  10. auto parse(Source s, dchar lbracket, dchar rbracket, dchar comma)
  11. auto parse(Source s, dchar lbracket, dchar rbracket, dchar keyval, dchar comma)

Parameters

Target

the enum type to convert to

s Source

the lvalue of the range to parse

doCount

the flag for deciding to report the number of consumed characters

Return Value

Type: auto
  • An enum of type Target if doCount is set to No.doCount
  • A tuple containing an enum of type Target and a size_t if doCount is set to Yes.doCount

Throws

A ConvException if type Target does not have a member represented by s.

Examples

import std.typecons : Flag, Yes, No, tuple;
enum EnumType : bool { a = true, b = false, c = a }

auto str = "a";
assert(parse!EnumType(str) == EnumType.a);
auto str2 = "a";
assert(parse!(EnumType, string, No.doCount)(str2) == EnumType.a);
auto str3 = "a";
assert(parse!(EnumType, string, Yes.doCount)(str3) == tuple(EnumType.a, 1));
