Struct ToolRule 

pub struct ToolRule {
    pub blocks: Vec<Identifier>,
    pub speed: Option<f32>,
    pub correct_for_drops: Option<bool>,
}

A single rule within a Tool component. Rules are evaluated in order; the first matching rule determines the speed/drop behavior.

Fields

blocks: Vec<Identifier>

The blocks this rule applies to (can be a tag like “#minecraft:mineable/pickaxe”, a single block like “minecraft:cobweb”, or a list of blocks).

speed: Option<f32>

The mining speed for these blocks. If None, uses the tool’s default_mining_speed.

correct_for_drops: Option<bool>

Whether the tool is “correct” for dropping items from these blocks. If None, falls back to the block’s requiresCorrectToolForDrops property.

Implementations

impl ToolRule

pub fn mines_and_drops(blocks: Vec<Identifier>, speed: f32) -> Self

Creates a rule that sets both mining speed and marks the tool as correct for drops.

pub fn denies_drops(blocks: Vec<Identifier>) -> Self

Creates a rule that explicitly denies drops (e.g., incorrect tool tier).

pub fn override_speed(blocks: Vec<Identifier>, speed: f32) -> Self

Creates a rule that only overrides the mining speed.

pub fn matches_block(&self, block_state_id: BlockStateId) -> bool

Checks if this rule matches a block state. Handles both direct block identifiers and block tags (prefixed with #).

Trait Implementations

impl Clone for ToolRule

fn clone(&self) -> ToolRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolRule

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

Formats the value using the given formatter.

impl PartialEq for ToolRule

fn eq(&self, other: &ToolRule) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
