Struct OsReleaseInfo 

pub struct OsReleaseInfo<'a> {
    map: HashMap<&'a str, &'a str>,
}

Parsed os-release file information.

Contains key-value pairs from an os-release file with methods to extract common fields like PRETTY_NAME and VERSION_ID.

Fields

map: HashMap<&'a str, &'a str>

Implementations

impl<'a> OsReleaseInfo<'a>

pub fn parse(content: &'a str) -> Self

Parses an /etc/os-release file

pub fn get_value(&self, keys: &[&str]) -> Option<String>

Looks up a key (like “PRETTY_NAME”) in the os-release file and returns the properly dequoted and unescaped value, if one exists.

pub fn get_pretty_name(&self) -> Option<String>

Returns the value of the PRETTY_NAME, NAME, or ID field, whichever is found first.

pub fn get_version(&self) -> Option<String>

Returns the value of the VERSION_ID or VERSION field, whichever is found first.

pub fn get_boot_label(&self) -> Option<String>

Combines get_pretty_name() with get_version() as specified in the Boot Loader Specification to produce a boot label. This will return None if we can’t find a name, but failing to find a version isn’t fatal.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
