Struct DepthBounded 

#[non_exhaustive]
pub struct DepthBounded {
    pub max_depth: usize,
    /* private fields */
}

At or above max_depth, only chooses expressions that are all terminals, guaranteeing termination. Below max_depth, behaves like RandomWalk.

Suited for generating “dummy” data for a UI or database seed that is valid but strictly bounded in size.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_depth: usize

Maximum expansion depth; at this depth only terminal-only expressions are chosen.

Implementations

impl DepthBounded

pub fn new(max_depth: usize) -> Self

Create a depth-bounded strategy with the given maximum depth.

pub fn from_seed(max_depth: usize, seed: [u8; 32]) -> Self

Create a strategy seeded from the given seed for reproducible generation.

Trait Implementations
