ok

convert errors to none

Synopsis

ok(val: any) -> any

Description

The ok function is inspired by the Rust language pattern of the same name and returns none when val is none or an error and otherwise returns val unmodified.

This function is useful when errors are expected and are to be explicitly managed with none operators.

Examples

# spq
values ok(10/this) ?? "bad value"
# input
2
0
# expected output
5
"bad value"

# spq
count() by key.ok() ?? "MISSING" | sort this
# input
{key:1}
{key:1}
{key:2}
{}
# expected output
{key:1,count:2}
{key:2,count:1}
{key:"MISSING",count:1}
