Struct FilterRule 

pub struct FilterRule { /* private fields */ }

One rule of a join request filter: the leading bytes of JoinEUI then DevEUI it matches, and what it does with a match.

Implementations

impl FilterRule

pub fn new(prefix: &[u8], action: FilterAction) -> Option<FilterRule>

Builds a rule.

Arguments

• prefix - the leading bytes of JoinEUI then DevEUI, most significant first as an EUI is written: three bytes match an organizationally unique identifier, eight a JoinEUI, and sixteen one device.
• action - what to do with a join request it matches.

Returns

The rule, or None for an empty prefix or one past sixteen bytes.

pub fn prefix(&self) -> &[u8]

Returns the bytes the rule matches.

Returns

The prefix, most significant first.

pub const fn action(&self) -> FilterAction

Returns what the rule does with a match.

Returns

The action.

pub fn matches(&self, join_eui: &[u8; 8], dev_eui: &[u8; 8]) -> bool

Reports whether a device’s identifiers begin with the rule’s prefix.

Arguments

• join_eui - the JoinEUI, most significant byte first.
• dev_eui - the DevEUI, most significant byte first.

Returns

true when every byte of the prefix matches.
