Struct Env 

pub struct Env<'a> {
    pub fps: f64,
    pub canvas: [f64; 2],
    pub size: [f64; 2],
    pub source: [f64; 2],
    pub in_: f64,
    pub out: f64,
    pub total: f64,
    pub source_in: f64,
    pub vars: Option<&'a Vars>,
}

What a range of frames is sampled in: the frame n (on the comp’s or timeline’s rate) maps to t = n / fps, lt = t − in, st = source_in + lt.

Fields

fps: f64

canvas: [f64; 2]

Canvas size, px.

size: [f64; 2]

Layer box, px.

source: [f64; 2]

Source display size, px.

in_: f64

out: f64

total: f64

Comp duration, s.

source_in: f64

vars: Option<&'a Vars>

Implementations

impl Env<'_>

pub fn builtins(&self, n: i64) -> [f64; 17]

The built-ins on frame n.

pub fn builtins_at(&self, t: f64) -> [f64; 17]

The built-ins at t comp seconds, between frames too (n is then fractional): for integrating a track over time.

Trait Implementations

impl<'a> Clone for Env<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Env<'a>

impl<'a> Debug for Env<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Env<'a>

fn default() -> Self

Returns the “default value” for a type.
