Trait SysvarSerialize 

Source 
pub trait SysvarSerialize:
    Default
    + Sysvar
    + SysvarId
    + Serialize
    + DeserializeOwned {
    // Provided methods
    fn size_of() -> usize { ... }
    fn from_account_info(
        account_info: &AccountInfo<'_>,
    ) -> Result<Self, ProgramError> { ... }
    fn to_account_info(&self, account_info: &mut AccountInfo<'_>) -> Option<()> { ... }
}
👎Deprecated since 4.3.0:

Use wincode::deserialize and check the sysvar account address

Available on crate feature bincode only.
Expand description

A type that holds sysvar data.

Provided Methods§

Source

fn size_of() -> usize

👎Deprecated since 4.3.0:

Use the sysvar crate’s SIZE constant or wincode::serialized_size

The size in bytes of the sysvar as serialized account data.

Source

fn from_account_info( account_info: &AccountInfo<'_>, ) -> Result<Self, ProgramError>

👎Deprecated since 4.3.0:

Use wincode::deserialize and check the account address

Deserializes the sysvar from its AccountInfo.

§Errors

If account_info does not have the same ID as the sysvar this function returns ProgramError::InvalidArgument.

Source

fn to_account_info(&self, account_info: &mut AccountInfo<'_>) -> Option<()>

👎Deprecated since 4.3.0:

Use wincode::serialize_into

Serializes the sysvar to AccountInfo.

§Errors

Returns None if serialization failed.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
