Rust Curve
rust
pub struct Curve<X: Scalar, C: Scalar>An owning, dynamically sized one-axis lookup curve.
new
rust
pub fn new(x_axis: Vec<X>, cells: Vec<C>) -> Result<Self, Error>Creates and validates a curve with one cell per X-axis point.
len
rust
pub fn len(&self) -> usizeReturns the number of X-axis points and cells.
is_empty
rust
pub fn is_empty(&self) -> boolReturns whether the curve has no points.
Valid curves are never empty, but this complements Self::len.
x_axis
rust
pub fn x_axis(&self) -> &[X]Returns the typed X-axis storage.
cells
rust
pub fn cells(&self) -> &[C]Returns the typed cell storage.
validate
rust
pub fn validate(&self) -> Result<(), Error>Revalidates all native table invariants.
lookup
rust
pub fn lookup(&self, x: f32) -> Result<f32, Error>Performs a clamped linear lookup at x.
x
rust
pub fn x(&self, index: usize) -> Result<X, Error>Reads one X-axis point through the native API.
cell
rust
pub fn cell(&self, index: usize) -> Result<C, Error>Reads one curve cell through the native API.
set_x
rust
pub fn set_x(&mut self, index: usize, value: X) -> Result<(), Error>Replaces one X-axis point while preserving strict ordering.
set_cell
rust
pub fn set_cell(&mut self, index: usize, value: C) -> Result<(), Error>Replaces one curve cell.
replace
rust
pub fn replace(&mut self, x_axis: &[X], cells: &[C]) -> Result<(), Error>Atomically validates and copies a complete same-sized curve snapshot.
