Struct CameraMetadata 

pub struct CameraMetadata {
    pub lens: Option<String>,
    pub iso: Option<u32>,
    pub aperture: Option<f32>,
    pub shutter_speed: Option<String>,
    pub focal_length_mm: Option<f32>,
    pub camera_make: Option<String>,
    pub camera_model: Option<String>,
}

Camera-specific technical metadata for a single clip.

Fields

lens: Option<String>

Lens make and model, e.g. "Zeiss Supreme Prime 50mm T1.5".

iso: Option<u32>

ISO sensitivity used during recording, e.g. 800.

aperture: Option<f32>

Aperture as a floating-point f-stop value, e.g. 2.8 for f/2.8.

shutter_speed: Option<String>

Shutter speed expressed as a fraction or angle string, e.g. "1/48" or "172.8°".

focal_length_mm: Option<f32>

Recorded focal length in millimetres, e.g. 50.0.

camera_make: Option<String>

Camera body make, e.g. "ARRI".

camera_model: Option<String>

Camera body model, e.g. "ALEXA Mini LF".

Implementations

impl CameraMetadata

pub fn new() -> Self

Creates an empty CameraMetadata.

pub fn with_lens(self, lens: impl Into<String>) -> Self

Builder-style setter for lens.

pub fn with_iso(self, iso: u32) -> Self

Builder-style setter for iso.

pub fn with_aperture(self, aperture: f32) -> Self

Builder-style setter for aperture.

pub fn with_shutter_speed(self, speed: impl Into<String>) -> Self

Builder-style setter for shutter_speed.

pub fn with_focal_length_mm(self, mm: f32) -> Self

Builder-style setter for focal_length_mm.

pub fn with_camera_make(self, make: impl Into<String>) -> Self

Builder-style setter for camera_make.

pub fn with_camera_model(self, model: impl Into<String>) -> Self

Builder-style setter for camera_model.

pub fn is_empty(&self) -> bool

Returns true if no fields are set.

pub fn approximate_ev(&self) -> Option<f32>

Returns an exposure-value (EV) hint based on ISO and aperture when both are present. EV = log2(aperture² / (ISO / 100)). This is a coarse indication; shutter speed is not included here because it is stored as a string and would require additional parsing.

Trait Implementations

impl Clone for CameraMetadata

fn clone(&self) -> CameraMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CameraMetadata

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

Formats the value using the given formatter.

impl Default for CameraMetadata

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CameraMetadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CameraMetadata

fn eq(&self, other: &CameraMetadata) -> 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.

impl Serialize for CameraMetadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
