Struct SvmFeatureConfig 

pub struct SvmFeatureConfig {
    pub enable: Vec<Pubkey>,
    pub disable: Vec<Pubkey>,
}

Overrides applied on top of LiteSVM’s mainnet-beta feature baseline.

surfpool’s SVM is constructed with the mainnet-beta feature set already active (see [litesvm::LiteSVM::mainnet_feature_set]). This struct expresses the user’s deltas relative to that baseline:

• features listed in enable are activated on top of the mainnet baseline (typically features that have not yet shipped to mainnet);
• features listed in disable are deactivated from the mainnet baseline (typically to reproduce older program behavior).

The default value is an empty override set, meaning “run with exactly the mainnet baseline.”

Fields

enable: Vec<Pubkey>

Features to activate on top of the mainnet baseline.

disable: Vec<Pubkey>

Features to deactivate from the mainnet baseline.

Implementations

impl SvmFeatureConfig

pub fn new() -> Self

Creates an empty override set (i.e. “mainnet baseline, no overrides”).

pub fn enable(self, feature: Pubkey) -> Self

Adds a feature to enable on top of the mainnet baseline.

pub fn disable(self, feature: Pubkey) -> Self

Adds a feature to disable from the mainnet baseline.

pub fn is_enabled(&self, feature: &Pubkey) -> Option<bool>

Checks if a feature should be enabled based on this configuration. Returns None if not explicitly configured (use default).

pub fn all_features_enabled() -> Self

Returns a config with every known agave feature gate explicitly enabled.

Mirrors the CLI’s --features-all flag.

Trait Implementations

impl Clone for SvmFeatureConfig

fn clone(&self) -> SvmFeatureConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SvmFeatureConfig

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

Formats the value using the given formatter.

impl Default for SvmFeatureConfig

fn default() -> SvmFeatureConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SvmFeatureConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SvmFeatureConfig

fn eq(&self, other: &SvmFeatureConfig) -> 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 SvmFeatureConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
