Struct ProtocolValidationContext 

pub struct ProtocolValidationContext {
    pub block_height: u64,
    pub network_params: NetworkParameters,
    pub validation_rules: ProtocolValidationRules,
    pub median_time_past: u64,
    pub network_time: u64,
    pub context_data: HashMap<String, String>,
}

Protocol-specific validation context

Fields

block_height: u64

Current block height

network_params: NetworkParameters

Current network parameters

validation_rules: ProtocolValidationRules

Protocol validation rules

median_time_past: u64

Median time-past used for time-based validation (BIP113)

This is populated by the node using recent headers and is threaded down to consensus for timestamp validation.

network_time: u64

Current adjusted network time (Unix timestamp)

This is populated by the node from its time source and used by consensus to enforce future timestamp limits.

context_data: HashMap<String, String>

Additional context data

Implementations

impl ProtocolValidationContext

pub fn new( version: ProtocolVersion, block_height: u64, ) -> Result<Self, ProtocolError>

Create validation context for a protocol version

pub fn is_feature_enabled(&self, feature: &str) -> bool

Check if a feature is enabled at current block height

pub fn get_max_size(&self, component: &str) -> u32

Get maximum allowed size for a component

Trait Implementations

impl Clone for ProtocolValidationContext

fn clone(&self) -> ProtocolValidationContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProtocolValidationContext

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProtocolValidationContext

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ProtocolValidationContext

fn eq(&self, other: &ProtocolValidationContext) -> 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.

impl Serialize for ProtocolValidationContext

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
