Implementations§

Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_has_role() -> [u8; 444]

Returns Some(index) if the account has the specified role, where index is the position of the account for that role, and can be used to query AccessControl::get_role_member(). Returns None if the account does not have the specified role.

§Arguments
  • e - Access to Soroban environment.
  • account - The account to check.
  • role - The role to check for.
Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_get_existing_roles() -> [u8; 332]

Returns a vector containing all existing roles. Defaults to empty vector if no roles exist.

§Arguments
  • e - Access to Soroban environment.
§Notes

This function returns all roles that currently have at least one member. The maximum number of roles is limited by MAX_ROLES.

Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_get_role_member_count() -> [u8; 264]

Returns the total number of accounts that have the specified role. If the role does not exist, returns 0.

§Arguments
  • e - Access to Soroban environment.
  • role - The role to get the count for.
Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_get_role_member() -> [u8; 704]

Returns the account at the specified index for a given role.

We do not provide a function to get all the members of a role, since that would be unbounded. If you need to enumerate all the members of a role, you can use AccessControl::get_role_member_count() to get the total number of members and then use AccessControl::get_role_member() to get each member one by one.

§Arguments
  • e - Access to Soroban environment.
  • role - The role to query.
  • index - The index of the account to retrieve.
§Errors

impl AccessControlSpec

Source

pub const fn spec_xdr_get_role_admin() -> [u8; 260]

Returns the admin role for a specific role. If no admin role is explicitly set, returns None.

§Arguments
  • e - Access to Soroban environment.
  • role - The role to query the admin role for.
Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_get_admin() -> [u8; 120]

Returns the admin account.

§Arguments
  • e - Access to Soroban environment.
Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_grant_role() -> [u8; 664]

Grants a role to an account.

§Arguments
  • e - Access to Soroban environment.
  • account - The account to grant the role to.
  • role - The role to grant.
  • caller - The address of the caller, must be the admin or have the RoleAdmin for the role.
§Errors
§Events
  • topics - ["role_granted", role: Symbol, account: Address]
  • data - [caller: Address]
Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_revoke_role() -> [u8; 784]

Revokes a role from an account. To revoke your own role, please use AccessControl::renounce_role() instead.

§Arguments
  • e - Access to Soroban environment.
  • account - The account to revoke the role from.
  • role - The role to revoke.
  • caller - The address of the caller, must be the admin or has the RoleAdmin for the role.
§Errors
§Events
  • topics - ["role_revoked", role: Symbol, account: Address]
  • data - [caller: Address]
Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_renounce_role() -> [u8; 608]

Allows an account to renounce a role assigned to itself. Users can only renounce roles for their own account.

§Arguments
  • e - Access to Soroban environment.
  • role - The role to renounce.
  • caller - The address of the caller, must be the account that has the role.
§Errors
§Events
  • topics - ["role_revoked", role: Symbol, account: Address]
  • data - [caller: Address]
Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_accept_admin_transfer() -> [u8; 1068]

Initiates the admin role transfer. Admin privileges for the current admin are not revoked until the recipient accepts the transfer. Overrides the previous pending transfer if there is one.

§Arguments
  • e - Access to Soroban environment.
  • new_admin - The account to transfer the admin privileges to.
  • live_until_ledger - The ledger number at which the pending transfer expires. If live_until_ledger is 0, the pending transfer is cancelled. live_until_ledger argument is implicitly bounded by the maximum allowed TTL extension for a temporary storage entry and specifying a higher value will cause the code to panic.
§Errors
§Events
  • topics - ["admin_transfer_initiated", current_admin: Address]
  • data - [new_admin: Address, live_until_ledger: u32]
§Notes
  • Authorization for the current admin is required.
Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_transfer_admin_role() -> [u8; 488]

Completes the 2-step admin transfer.

§Arguments
  • e - Access to Soroban environment.
§Events
  • topics - ["admin_transfer_completed", new_admin: Address]
  • data - [previous_admin: Address]
§Errors
Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_set_role_admin() -> [u8; 524]

Sets admin_role as the admin role of role.

§Arguments
  • e - Access to Soroban environment.
  • role - The role to set the admin for.
  • admin_role - The new admin role.
§Events
  • topics - ["role_admin_changed", role: Symbol]
  • data - [previous_admin_role: Symbol, new_admin_role: Symbol]
§Errors
§Notes
  • Authorization for the current admin is required.
Source§

impl AccessControlSpec

Source

pub const fn spec_xdr_renounce_admin() -> [u8; 540]

Allows the current admin to renounce their role, making the contract permanently admin-less. This is useful for decentralization purposes or when the admin role is no longer needed. Once the admin is renounced, it cannot be reinstated.

§Arguments
  • e - Access to Soroban environment.
§Errors
§Events
  • topics - ["admin_renounced", admin: Address]
  • data - []
§Notes
  • Authorization for the current admin is required.
