Function select_settings_candidates

Source 
pub fn select_settings_candidates<'a, I>(
    possible_settings: I,
    constraints: &SanitizedMediaTrackConstraints,
    exposure_mode: DeviceInformationExposureMode,
) -> Result<Vec<&'a MediaTrackSettings>, SelectSettingsError>

Expand description

This function implements steps 1-5 of the SelectSettings algorithm as defined by the W3C spec: https://www.w3.org/TR/mediacapture-streams/#dfn-selectsettings

Step 6 (tie-breaking) is omitted by this implementation and expected to be performed manually on the returned candidates. For this several implementation of TieBreakingPolicy are provided by this crate.
