Struct ValidationGraph 

pub struct ValidationGraph<const N: usize> { /* private fields */ }

A stack-allocated validation graph with up to N nodes.

Nodes execute sequentially. The graph can run in two modes:

• Fail-fast (run): stops at first error
• Accumulate (run_all): runs all nodes, returns first error

Implementations

impl<const N: usize> ValidationGraph<N>

pub fn new() -> Self

Create an empty validation graph.

pub fn add(&mut self, node: ValidateFn) -> Result<(), ProgramError>

Add a validation node.

pub fn len(&self) -> usize

Number of nodes in the graph.

pub fn is_empty(&self) -> bool

Whether the graph has no nodes.

pub fn run(&self, ctx: &ValidationContext<'_>) -> ProgramResult

Run all validations, fail-fast on first error.

pub fn run_all(&self, ctx: &ValidationContext<'_>) -> ProgramResult

Run all validations, accumulate results. Returns the first error found.

Trait Implementations

impl<const N: usize> Default for ValidationGraph<N>

fn default() -> Self

Returns the “default value” for a type.

impl<const M: usize> Validatable for ValidationGraph<M>

fn validate(&self, ctx: &ValidationContext<'_>) -> ProgramResult

Run validation against the given context.
