Struct GlibcVersion 

pub struct GlibcVersion {
    pub major: u32,
    pub minor: u32,
    pub patch: u32,
}

A GLIBC_x.y release the host’s libc must reach for an artifact to load. Three components because real tags carry one when they need it — GLIBC_2.2.5 exists — and 2.2 < 2.2.5 must not hold.

Fields

major: u32

The major component — 2 for every glibc release in the wild.

minor: u32

The minor component.

patch: u32

The patch component, 0 when the tag carries only major.minor.

Implementations

impl GlibcVersion

pub fn parse_version_tag(name: &[u8]) -> Option<Self>

Parse one GLIBC_x.y[.z] version-needed name — the bytes an ELF SHT_GNU_VERNEED aux entry names, like b"GLIBC_2.28". Returns None for anything else: other namespaces (GCC_3.0, GLIBCXX_3.4.29), and glibc’s own non-numeric names (GLIBC_PRIVATE, GLIBC_ABI_DT_RELR) that pin an ABI property rather than a release.

Trait Implementations

impl Clone for GlibcVersion

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for GlibcVersion

impl Debug for GlibcVersion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GlibcVersion

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for GlibcVersion

major.minor, plus .patch only when nonzero — 2.28, 2.2.5. The bare two-component rendering is the form every existing release tag and the gnu_get_libc_version string share.

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

Formats the value using the given formatter.

impl Eq for GlibcVersion

impl FromStr for GlibcVersion

"{major}.{minor}[.{patch}]" — the same shape [Display] writes, so GlibcVersion::from_str(v.to_string().as_str()) round-trips. Anything else — empty components, non-digits, a fourth component — fails.

type Err = GlibcVersionParseError

The associated error which can be returned from parsing.

fn from_str(text: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for GlibcVersion

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for GlibcVersion

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for GlibcVersion

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for GlibcVersion

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for GlibcVersion

Wire form is the Display string: "2.28", not a two-field object — the row reads like a version, not a struct.

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
