Struct primitives::filter::LogFilterParams

pub struct LogFilterParams {
    pub address: Option<Vec<Address>>,
    pub topics: Vec<Option<Vec<H256>>>,
    pub trusted: bool,
    pub space: Space,
}

Log event Filter.

Fields

address: Option<Vec<Address>>

Search addresses.

If None, match all. If specified, log must be produced by one of these addresses.

topics: Vec<Option<Vec<H256>>>

Search topics.

If None, match all. If specified, log must contain one of these topics.

trusted: bool

Indicate if the log filter can be trusted, so we do not need to check other fields.

It is false if the Filter is constructed from RPCs, and true if it is generated within the process with trusted logics.

space: Space

Space: Conflux or Ethereum.

Log must be produced in this space.

Implementations

impl LogFilterParams

pub fn bloom_possibilities(&self) -> Vec<Bloom>

Returns combinations of each address and topic.

pub fn matches(&self, log: &LogEntry) -> bool

Returns true if given log entry matches filter.

Trait Implementations

impl Clone for LogFilterParams

fn clone(&self) -> LogFilterParams

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LogFilterParams

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

Formats the value using the given formatter.

impl Default for LogFilterParams

fn default() -> Self

Returns the “default value” for a type.

impl Hash for LogFilterParams

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LogFilterParams

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

This method tests for self and other values to be equal, and is used by ==.

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

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