Struct BlockCountMismatch

Source

pub struct BlockCountMismatch {
    pub family: String,
    pub expected: usize,
    pub got: usize,
}

Expand description

A block-count arity mismatch: a family that needs exactly expected parameter blocks was handed got of them.

This is the neutral carrier produced by validate_block_count; each module converts it into its own error type via From<BlockCountMismatch>.

Fields§

§family: String

Human-readable family / term name used as the message prefix.

§expected: usize

Number of parameter blocks the family requires.

§got: usize

Number of parameter blocks that were actually supplied.

Implementations§

Source §

impl BlockCountMismatch

Source

pub fn message(&self) -> String

The canonical arity-mismatch message, e.g. "FooFamily expects 2 blocks, got 1" (plural) or "BarFamily expects 1 block, got 0" (singular when expected == 1).
