pub struct FieldElement(pub FieldElement);Expand description
A wrapper around FieldElement to enable FFI interoperability.
FieldElement represents an element in a finite field used in the World ID Protocol’s
zero-knowledge proofs. This wrapper allows the type to be safely passed across FFI boundaries
while maintaining proper serialization and deserialization semantics.
Field elements are typically 32 bytes when serialized.

§0: FieldElementImplementations§
Source§impl FieldElement
impl FieldElement
Sourcepub fn from_bytes(bytes: Vec<u8>) -> Result<Self, WalletKitError>
pub fn from_bytes(bytes: Vec<u8>) -> Result<Self, WalletKitError>
Creates a FieldElement from raw bytes (big-endian).
§Errors
Returns an error if the bytes cannot be deserialized into a valid field element.
Sourcepub fn from_u64(value: u64) -> Self
pub fn from_u64(value: u64) -> Self
Creates a FieldElement from a u64 value.
This is useful for testing or when working with small field element values.
Sourcepub fn to_bytes(&self) -> Vec<u8> ⓘ
pub fn to_bytes(&self) -> Vec<u8> ⓘ
Serializes the field element to bytes (big-endian).
Returns a byte vector representing the field element.
Sourcepub fn try_from_hex_string(hex_string: &str) -> Result<Self, WalletKitError>
pub fn try_from_hex_string(hex_string: &str) -> Result<Self, WalletKitError>
Creates a FieldElement from a hex string.
The hex string can optionally start with “0x”.
§Errors
Returns an error if the hex string is invalid or cannot be parsed.
Sourcepub fn to_hex_string(&self) -> String
pub fn to_hex_string(&self) -> String
Converts the field element to a hex-encoded, padded string.
Methods from Deref<Target = CoreFieldElement>§
pub const ZERO: FieldElement
pub const ONE: FieldElement
Sourcepub fn to_be_bytes(&self) -> [u8; 32]
pub fn to_be_bytes(&self) -> [u8; 32]
Returns the 32-byte big-endian representation of this field element.
