str2enum

Return the enumeration constant associated with an output ndarray data type policy string.

Usage

var str2enum = require( '@stdlib/ndarray/base/output-policy-str2enum' );

str2enum( policy )

Returns the enumeration constant associated with an output ndarray data type policy string.

var v = str2enum( 'same' );
// returns <number>

If unable to resolve an enumeration constant, the function returns null.

var v = str2enum( 'beep' );
// returns null

Notes

Downstream consumers of this function should not rely on specific integer values (e.g., SAME == 0). Instead, the function should be used in an opaque manner.

Examples

var str2enum = require( '@stdlib/ndarray/base/output-policy-str2enum' );

var v = str2enum( 'same' );
// returns <number>

v = str2enum( 'promoted' );
// returns <number>

v = str2enum( 'floating_point' );
// returns <number>

v = str2enum( 'real_floating_point' );
// returns <number>

v = str2enum( 'signed_integer' );
// returns <number>

v = str2enum( 'unsigned_integer' );
// returns <number>

v = str2enum( 'complex_floating_point' );
// returns <number>

v = str2enum( 'integer' );
// returns <number>
