Struct Selection 

pub struct Selection<T> {
    pub include: T,
    pub exclude: Option<T>,
}

Fields

include: T

Filters where matching values should be included in the response Default::default() means include everything

exclude: Option<T>

Filters where matching values should be excluded from the response None means exclude nothing, Some(Default::default()) means exclude everything

Implementations

impl<T> Selection<T>

pub fn new(filter: T) -> Self

Create a new selection with the given filter.

Arguments

• filter - The filter to include in the selection

Examples

use hypersync_net_types::{LogSelection, LogFilter};

// Create a selection that includes the filter

let selection = LogSelection::new(
    LogFilter::all().and_address(["0xdadB0d80178819F2319190D340ce9A924f783711"])?,
);

Ok::<(), anyhow::Error>(())

pub fn and_not(self, filter: T) -> Self

Add a filter to exclude from the selection

Arguments

• filter - The filter to exclude from the selection

Examples

use hypersync_net_types::{LogSelection, LogFilter};

// Create a selection with a filter that matches any log. (or your own filter)
let all = LogSelection::new(LogFilter::all());

// Create a selection that excludes only logs from a specific address
let selection = all.and_not(
    LogFilter::all().and_address(["0xa0b86a33e6c11c8c0c5c0b5e6adee30d1a234567"])?,
);

Ok::<(), anyhow::Error>(())

pub fn or(self, selection: Self) -> AnyOf<Self>

Combine this selection with another selection using logical OR.

This creates an AnyOf type that will match if either this selection or the provided selection matches.

Arguments

• selection - Another selection to combine with this one

Returns

An AnyOf<Self> that represents the logical OR of both selections

Examples

use hypersync_net_types::{LogSelection, LogFilter};

// Create two different selections
let selection1 = LogSelection::new(LogFilter::all())
    .and_not(LogFilter::all().and_address(["0xdadB0d80178819F2319190D340ce9A924f783711"])?);
let selection2 = LogSelection::new(
    LogFilter::all().and_address(["0xa0b86a33e6c11c8c0c5c0b5e6adee30d1a234567"])?,
);

// Combine them with OR - matches logs from either address
let combined = selection1.or(selection2);

fn clone(&self) -> Selection<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Selection<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Selection<T>

fn default() -> Selection<T>

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Selection<T>

where T: Deserialize<'de> + Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl<T> From<Selection<T>> for AnyOf<Selection<T>>

fn from(selection: Selection<T>) -> AnyOf<Selection<T>>

Converts to this type from the input type.

impl<T> From<T> for Selection<T>

fn from(include: T) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for Selection<T>

fn eq(&self, other: &Selection<T>) -> 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.

where T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
