Struct ContractSourceMetadata 

pub struct ContractSourceMetadata {
    pub version: Option<String>,
    pub link: Option<String>,
    pub standards: Vec<Standard>,
    pub build_info: Option<BuildInfo>,
}

The struct provides information about deployed contract’s source code and supported standards.

Contract source metadata follows NEP-330 standard for smart contracts

See the documentation of Contract::contract_source_metadata on how to query this for a contract via this crate

Fields

version: Option<String>

Optional version identifier, typically a semantic version

Examples:

// Semantic version
Some("1.0.0".into())

// Git commit
Some("39f2d2646f2f60e18ab53337501370dc02a5661c".into())

link: Option<String>

Optional URL to source code repository/tree

Examples:

// GitHub URL
Some("https://github.com/org/repo/tree/8d8a8a0fe86a1d8eb3bce45f04ab1a65fecf5a1b".into())

// GitHub URL
Some("https://github.com/near-examples/nft-tutorial".into())

// IPFS CID
Some("bafybeiemxf5abjwjbikoz4mc3a3dla6ual3jsgpdr4cjr3oz3evfyavhwq".into())

standards: Vec<Standard>

List of supported NEAR standards (NEPs) with their versions

This field is an addition of 1.1.0 NEP-330 revision

Examples:

This field will always include NEP-330 itself:

// this is always at least 1.1.0
vec![Standard { standard: "nep330".into(), version: "1.1.0".into() }]

vec![Standard { standard: "nep330".into(), version: "1.2.0".into() }]

build_info: Option<BuildInfo>

Optional details that are required for formal contract WASM build reproducibility verification

This field is an addition of 1.2.0 NEP-330 revision

Trait Implementations

impl Clone for ContractSourceMetadata

fn clone(&self) -> ContractSourceMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContractSourceMetadata

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

Formats the value using the given formatter.

impl Default for ContractSourceMetadata

fn default() -> ContractSourceMetadata

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ContractSourceMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ContractSourceMetadata

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ContractSourceMetadata

impl StructuralPartialEq for ContractSourceMetadata
