Enum FilterBlockOption 

pub enum FilterBlockOption {
    Range {
        from_block: Option<BlockNumberOrTag>,
        to_block: Option<BlockNumberOrTag>,
    },
    AtBlockHash(FixedBytes<32>),
}

Represents the target range of blocks for the filter

Variants

Range

Represents a range of blocks with optional from and to blocks

Note: ranges are considered to be inclusive

Fields

from_block: Option<BlockNumberOrTag>

The block number or tag this filter should start at.

to_block: Option<BlockNumberOrTag>

The block number or that this filter should end at.

AtBlockHash(FixedBytes<32>)

The hash of the block if the filter only targets a single block

Implementations

impl FilterBlockOption

pub const fn get_to_block(&self) -> Option<&BlockNumberOrTag>

Returns the to_block value, if any

pub const fn get_from_block(&self) -> Option<&BlockNumberOrTag>

Returns the from_block value, if any

pub const fn as_range( &self, ) -> (Option<&BlockNumberOrTag>, Option<&BlockNumberOrTag>)

Returns the range (from_block, to_block) if this is a range filter.

pub const fn as_block_hash(&self) -> Option<&FixedBytes<32>>

Returns the block hash if this is a block hash filter.

pub const fn is_range(&self) -> bool

Returns true if this is a range filter.

pub const fn is_block_hash(&self) -> bool

Returns true if this is a block hash filter.

pub fn ensure_valid_block_range(&self) -> Result<(), FilterBlockError>

Ensure block range validity

pub const fn with_from_block( &self, block: BlockNumberOrTag, ) -> FilterBlockOption

Sets the block number this range filter should start at.

pub const fn with_to_block(&self, block: BlockNumberOrTag) -> FilterBlockOption

Sets the block number this range filter should end at.

pub const fn with_block_hash(&self, hash: FixedBytes<32>) -> FilterBlockOption

Pins the block hash this filter should target.
