Struct forest_filecoin::rpc::methods::eth::types::EthFilterSpec

pub struct EthFilterSpec {
    pub from_block: Option<String>,
    pub to_block: Option<String>,
    pub address: Vec<EthAddress>,
    pub topics: EthTopicSpec,
    pub block_hash: Option<EthHash>,
}

Represents a filter specification for querying Ethereum event logs. This struct can be used to specify criteria for filtering Ethereum event logs based on block range, address, topics, and block hash. It is useful for making requests to Ethereum nodes to fetch logs that match certain conditions.

Fields

• from_block - Optional field interpreted as an epoch (in hex):

  • "latest": latest mined block.
  • "earliest": first block.
  • "pending": blocks that have not yet been mined. If omitted, the default value is "latest". This field is skipped during serialization if None.

• to_block - Optional field interpreted as an epoch (in hex):

  • "latest": latest mined block.
  • "earliest": first block.
  • "pending": blocks that have not yet been mined. If omitted, the default value is "latest". This field is skipped during serialization if None.

• address - Actor address or a list of addresses (Vec<EthAddress>) from which event logs should originate. If the filter needs to match a single address, it can be specified as single element vector. This field is required and cannot be omitted.

• topics - List of topics (EthTopicSpec) to be matched in the event logs.

• block_hash - Optional field specifying a block hash (Hash) Restricts event logs returned to those emitted from messages contained in this tipset. When block_hash is provided, neither from_block nor to_block can be specified. This field is skipped during serialization if None. the spec.

Fields

from_block: Option<String>

to_block: Option<String>

address: Vec<EthAddress>

topics: EthTopicSpec

block_hash: Option<EthHash>
