List parse error.

Variants

IoError(Error)

An IO error.

ContainsAnEmptyIndexOrRange

Contains an empty index or range.

CouldNotParseIndex(&'static str, String, ParseIntError)

Could not parse index.

ContainsMisSortedIndices(u16, u16)

Contains mis-sorted indices.

RangeIsNotAnAscendingRangeWithMoreThanOneElement(u16, u16)

Range is not an ascending range with more than one element.

Methods

impl ListParseError

pub fn parse_linux_list_string<Mapper: Fn(u16) -> R, R: Ord>(     linux_list_string: &str,     mapper: Mapper ) -> Result<BTreeSet<R>, ListParseError>

Parses a Linux list string used for cpu sets, core masks and NUMA nodes such as "2,4-31,32-63" and "1,2,10-20,100-2000:2/25" (see https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html for an awful description of this mad syntax).

Returns a BTreeSet with the zero-based indices found in the string. For example, "2,4-31,32-63" would return a set with all values between 0 to 63 except 0, 1 and 3.
