Struct GStreamerProbe 

pub struct GStreamerProbe {
    pub gst_launch: Option<String>,
    pub gst_discoverer: Option<String>,
    pub plugins: BTreeMap<String, bool>,
    pub path: String,
}

Structured GStreamer probe result.

gst_launch / gst_discoverer contain the trimmed --version output when the binary is callable, or None when the spawn fails. plugins is the requested-plugin map (from probe_with_plugins); empty when probe is used.

Fields

gst_launch: Option<String>

gst-launch-1.0 --version first line, or None if the spawn failed (binary missing, permission denied, etc.).

gst_discoverer: Option<String>

gst-discoverer-1.0 --version first line, or None.

plugins: BTreeMap<String, bool>

Requested-plugin presence map (plugin-name → present?). Filled only by probe_with_plugins. Sorted by name for deterministic output.

path: String

Snapshot of PATH at probe time. Useful in CI logs when a previously-working install starts spawning ENOENT.

Implementations

impl GStreamerProbe

pub fn is_available(&self) -> bool

True when both gst-launch-1.0 and gst-discoverer-1.0 are callable. Plugin-presence is not considered — explicit plugin requirements should be checked via Self::has_plugin.

pub fn has_plugin(&self, name: &str) -> bool

True when the named plugin was checked AND present. Returns false for both “checked-but-missing” and “not-checked.” Callers wanting to distinguish should inspect Self::plugins directly.

Trait Implementations

impl Clone for GStreamerProbe

fn clone(&self) -> GStreamerProbe

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GStreamerProbe

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

Formats the value using the given formatter.

impl Display for GStreamerProbe

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

Formats the value using the given formatter.

impl PartialEq for GStreamerProbe

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
